Low Ionic Strength Screen (LISS)
Applications
- Crystallization screen for intact monoclonal antibodies, monoclonal antibody fragments, & proteins less soluble at low ionic strength
Features
- Screen a complete pH profile (2-12) at low ionic strength
- Requires only 25-110 microliters of sample.
- Enhanced temperature effects due to low ionic strength
- Monodisperse PEG 3,350
Description
The Low Ionic Strength Screen is effective in determining the preliminary crystallization conditions of intact monoclonal antibodies.1 However, this screen is not just an intact antibody screen. The screen has effectively determined the preliminary crystallization conditions for numerous monoclonal antibody fragments as well as other soluble proteins.
The screen should be utilized as a low ionic strength crystallization screen for proteins where this strategy could be effective in determining preliminary crystallization screens.
In this screen, the concentration of a high purity, monodisperse PEG 3,350 is varied from 4 to 24% w/v (4, 8, 12, 16, 20 and 24% w/v) versus a pH range of 2 to 12 (2, 3, 3.5, 4, 4.5, 5, 5.5, 6.0, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 11, 12). Stock buffer concentrations are 50 mM. Final buffer concentration in the drop is typically 10 mM.
Unique features of this screen: (1) Low ionic strength. Buffer concentration is supplied as 50 mM, resulting in an initial drop concentration of 10 mM (Drop = 4 µl sample, 2 µl buffer, 5 µl precipitant). (2) The Polyethylene glycol (PEG) 3,350 is a special, high-purity, monodisperse preparation with an Mr of 3,300-3,400. Most PEGs of this molecular weight have an Mr of plus or minus 500 rather than 50. (3) An extremely broad range of pH 2 to 12 is sampled. At low ionic strength, the effects of pH and temperature upon sample solubility are amplified. Hence this screen allows one to critically evaluate the effects of temperature and pH upon sample solubility and crystallization. It is recommended the screen be repeated at several temperatures between 4°C and 37°C to take advantage of the low ionic strength feature.
The format of this screen is different than other screens offered by Hampton Research. The screen is supplied as a set of eighteen 50 mM buffers, six PEG 3,350 concentrations, and a single dehydrant, PEG 3,350. This formulation allows one to screen up to 108 conditions if desired. The formulation is designed to offer options. Coarse sample of pH and/or precipitant concentration can be performed with 24 or even 12 drops. This will eliminate large regions of sampling space and conserve sample. Subsequent screens and perhaps even optimization can encompass an increasingly finer grid matrix of pH, precipitant concentration as well as other variables significant for sample crystallization. The protocol requires the following pipetting steps for a typical vapor diffusion experiment: (1) Pipet dehydrant to reservoir. (2) Pipet drop. (3) Pipet buffer to drop. (4) Pipet precipitant to drop.
Each kit contains 24 unique reagents of varying pH and PEG 3,350 concentration. Buffers of 50 mM are supplied for pH 2, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 11, and 12 in 1 ml volumes. The precipitant Polyethylene glycol 3350 is supplied as 4, 8, 12, 16, 20, and 24% w/v in 1 ml volumes. Dehydrant is available separately as 200 ml of 24% w/v PEG 3,350 (catalog number HR2-519). Combining each pH and precipitant supplied can generate 108 crystallization screening conditions. All solutions are formulated using ultra-pure water and are sterile filtered.
Note: Crystallization kit (HR2-120) and Dehydrant/reservoir solution (HR2-519) are sold separately. Both items are needed to perform the screen.

TCEP hydrochloride蛋白结晶试剂盒Hampton Research
Hampton Research蛋白结晶试剂盒
Products > Optimize Reagents > Optimize – Reducing Agent > TCEP hydrochloride
TCEP hydrochloride
Applications
- Stable reducing agent for crystallization trials
Features
- Highly soluble
- Odorless and non-volatile
- Effective at acidic and alkaline pH
Description
TCEP hydrochloride is Tri(2-carboxyethyl)phosphine hydro-chloride.
TCEP hydrochloride is an odorless, non-volatile reducing agent that is more stable and effective than DTT or 2-Mercaptoethanol. Unlike DTT, TCEP hydrochloride retains its reducing power at acid pHs (pH 5) and at pHs above 7.5 and is stable in air. TCEP hydrochloride is soluble in water to 310 grams per liter. For most applications, 5-50 mM TCEP provides sufficient molar excess to effectively reduce peptide or protein disulfide bonds within a few minutes at room temperature. TCEP hydrochloride is unreactive toward other functional groups found in proteins. Unlike DTT (dithiothreitol), TCEP hydrochloride does not contain a free thiol, and therefore does not require removal before reaction with thiol-reactive reagents. TCEP reduces disulfides but apparently not mercury-thiol bonds. TCEP hydrochloride is compatible with many heavy atoms and may be used during heavy atom derivatization. TCEP hydrochloride is more stable at a higher pH and at higher temperatures than is DTT and for a longer period of time in buffers without metal chelators such as EGTA. With TCEP, removal of the reducing agent is not necessary prior to most applications, (e.g. histidine-tagged protein purification, protein crystallization).
TCEP is typically very soluble in aqueous buffers at nearly any pH. Therefore, working concentrations and 10X stock solutions may be readily prepared in most aqueous buffers. TCEP is stable in aqueous, acidic, and basic solutions. When TCEP is dissolved directly in water, the resulting pH is approximately 2.5. TCEP is not very stable in phosphate buffers, especially at neutral pH. Therefore, if TCEP is to be used in PBS buffers, prepare the working solution immediately before use. TCEP may be used as a substitute loading buffer for SDS-PAGE; use a final concentration of 50 mM TCEP. Since TCEP is charged in solution, it is not compatible for use in isoelectric focusing.
A 10 mM TCEP hydrochloride concentration can reduce the pH of a 100 mM buffer by approximately 0.5 pH units; 1 mM TCEP hydrochloride concentration reducing the pH of a 100 mM buffer by 0.05 pH units.
Stability in Solution
TCEP is stable in aqueous acidic and basic solutions. When TCEP is dissolved directly in water the resulting pH is 2.5. Various buffers may be used for the reductions. Studies indicate that no change in concentration occurs after 24 hour incubation at room temperature in 100 mM HCL, 100 mM NaOH, or any of the following 50 mM buffers Tris HCl (pH 7.5, 8.5, 9.5), HEPES(pH 6.8, 8.2), Borate(pH 8.2, 10.2), and CAPS (pH 9.7, 11.1). Even after weeks in these buffers, less than 20% of the TCEP was oxidized.
TCEP is not particularly stable in phosphate buffers, especially at neutral pH. Experiments indicate that TCEP completely oxidizes within 72 hours in 0.35M phosphate-buffered saline (PBS), pH 7.0. Approximately 50% oxidation occurs in the same amount of time in 0.15M PBS, pH 8.0. Only minimal oxidation occurs in PBS at pH > 10.5 or < 6.0. Therefore, if TCEP is to be used in PBS buffers, prepare the working solution immediately before use.
Solid TCEP hydrochloride is supplied packaged in argon to minimize oxidation.

Micro-Tools Set
Applications
- Precision instruments for crystal manipulation
Features
- Made from chemical-resistant hardened tool steel
- Interchangeable tools tips
- Set includes wooden storage case
Description
Micro-Tools™ are the smallest available precision instruments for laboratory use. These tools are realistically proportioned for macromolecular and small molecule crystallization work. The high quality, precision Micro-Tools ease microscopic manipulations. The eight specifically engineered Micro-Tools are useful in a variety of applications in the crystallization lab. Eight tools, a handle and wood storage box.
Micro-Tools are designed to be versatile as well as useful for specific crystallization manipulations. For example, the Micro-Scale is very useful for measuring crystal dimensions as well as serving as a way to record the dimensions by photography for reference or publication. The Micro-Chisel and Micro-Spade are helpful for separating and splitting blade and whisker clusters during seeding or mounting. The Micro-Prober and Micro-Needle come in handy when probing precipitate or when manipulating small or large crystals for seeding as well as during mounting. The Micro-Spatula can be used to move crystals as well as split single crystals or clusters. The Micro-Scraper is helpful when working with very small crystals.
The Micro-Tools Set is indispensable during crystal observation, manipulation, seeding, and mounting. The set includes a single anodized aluminum handle which holds each of the eight unique tips, all supplied in an attractive alderwood instrument case. The case provides protective storage of the Micro-Tools as well as a convenient carrying case.
The tips are constructed from hardened tungsten steel and are resistant to most common reagents used for crystal growth. The threaded tool tips are easily interchanged with the threaded aluminum handle. Then overall length of the handle only is 120 mm. The diameter of the tool shaft is 0.25 mm – 0.5 mm (0.01 – 0.02 inches). The actual dimension at the very tip of the tool will vary with the particular tool design.

Izit Crystal Dye
Applications
- Differentiate protein crystals from salt crystals
Features
- 0.22 micron sterile filtered solution
- Small molecule dye penetrates solvent channels of macromolecular crystals, coloring the crystals blue
- Salt crystals cannot absorb Izit and remain colorless
- Differentiate protein and non-protein based phase separation
- Formulated in Type 1+ ultrapure water: 18.2 megaohm-cm resistivity at 25°C, < 5 ppb Total Organic Carbon, bacteria free (<1 Bacteria (CFU/ml)), pyrogen free (<0.03 Endotoxin (EU/ml)), RNase-free (< 0.01 ng/mL) and DNase-free (< 4 pg/µL)
Description
A crystal! Is it protein or is it salt?
Have you ever asked yourself this question? Sure you could mount the crystal in question and take a quick look at the diffraction pattern but perhaps you′re too lazy or you don′t have an x-ray facility. Well, there′s always the crush test. One simply takes a MicroTool™ or Crystal Probe™ and crushes the suspect crystal. A click or solid crunch is indicative of salt while a powder or silent destruction might indicate one just destroyed a perfectly good protein crystal. Izit is here to help. Simply place 1 µl of Izit in the sample drop and wait for an hour or so. Izit is a small molecule dye which will fill the solvent channels in protein crystals, coloring the crystals blue. With the appropriate dilution, Izit will in fact leave a clear drop with blue crystals, as illustrated in the picture above. Salt crystals do not possess these large solvent channels. Therefore, Izit cannot enter the crystal, leaving one with a clear crystal and a blue drop. Izit is especially nice for small microcrystals or questionable precipitate. The 0.5 ml vial of Izit is sufficient for more than thousands of crystallization drops.
Each Izit vial contains 0.5 ml of Izit dye. All solutions are formulated using ultra-pure water and are sterile filtered. Crystallization accessories are sold separately.

Micro-Tools II Set
Applications
- Precision instruments for crystal manipulation
Features
- Made from chemical resistant tungsten steel & hardened tool steel
- Interchangeable tools tips
- 8 unique tools designed to extend the original Micro-Tools set
- Set includes wooden storage case
Description
Micro-Tools II™ Set is an extension to the smallest available precision instruments for laboratory use. These tools are realistically proportioned for macromolecular and small molecule crystallization work. The high quality, precision Micro-Tools II ease microscopic manipulations. The eight specifically engineered Micro-Tools II are useful in a variety of applications in the crystallization lab. Eight tools, a handle and wood storage box.
The Micro-Tools II are designed to be versatile as well as useful for specific crystallization manipulations. For example, the Micro-Manipulator is handy for manipulating long, thin blades or for separating long, thin blade clusters. Awkward positions encountered during crystal manipulation can sometimes be avoided using tools with an unusual and flexible approach angle such as the Micro-Prober 90° and the Micro-Hook 90°. Seeding experiments can be performed using the Micro-Brush. The Ultra Micro-Needles are extremely delicate tools crafted from 5 micron radius tungsten that are very handy for seeding as well as manipulations requiring a soft, fine, and controlled touch.
The Micro-Tools II Set is indispensable during crystal observation, manipulation, seeding, and mounting. The set includes a single anodized aluminum handle which holds each of the eight unique tips, all supplied in an attractive alderwood instrument case. The case provides protective storage of the Micro-Tools as well as a convenient carrying case.
The tips are constructed from hardened tungsten steel and are resistant to most common reagents used for crystal growth. The threaded tool tips are easily interchanged with the threaded aluminum handle. Then overall length of the handle only is 120 mm. The diameter of the tool shaft is 0.25 mm – 0.5 mm (0.01 – 0.02 inches). The actual dimension at the very tip of the tool will vary with the particular tool design. Each of the Micro-Tools II Set is also available individually, as is the Handle HR4-829 and Carrying Case HR4-831.

Microbatch 72 Well Plate (Greiner)
Applications
- Microbatch crystallization
Features
- Conical, flat bottom wells
- Hydrophobic or hydrophilic versions
- Compact size
- Supplied with cover
- Terasaki plate
Description
The 72 Well Microbatch Plate consists of a 6 by 12 well layout. Paraffin, Silicon, or Al’s Oil is poured into the trough area of the plate, submerging all 72 wells under oil. Sample and reagent are then pipetted into each of the wells. The plate is available as a plasma-treated, hydrophilic version for screening or an untreated, hydrophobic version for optimization. The hydrophilic version gives better liquid handling with small volumes, while the hydrophobic version reduces crystal nucleation and helps to prevent the crystals from sticking to the plastic.
• Plate dimensions: 83.3 mm x 58.0 mm x 10.0 mm
• Conical well with 11 µl drop volume
• Flat bottom well diameter: 1.3 mm
• Supplied with cover
