PEG/pH • PEG/pH 2 • PEG/pH HT
Applications
- Crystallization screen where Polyethylene glycol 4,000 and buffers sample an acidic to neutral, and/or neutral to alkaline pH
Features
- Developed at Hampton Research
- PEG/pH samples pH 3.5 – 7.4 in 0.2 M buffer
- PEG/pH 2 samples pH 6.4 – 9.6 in 0.2 M buffer
- PEG/pH HT samples pH 3.5 – 9.6 in 0.2 M buffer
- Polyethylene glycol 4,000 – primary reagent
- PEG/pH & PEG/pH 2 each utilize 10 unique buffers, 0.2 M – secondary reagent
- PEG/pH HT 20 unique buffers, 0.2 M – secondary reagent
- Compatible with vapor diffusion, microbatch, free interface diffusion
Description
pH is an effective solubility, stability and crystallization variable because most proteins demonstrate pH dependent solubility minima and will solubilize, precipitate, or crystallize at particular pH values or in the presence of specific buffers. The solubility minima may correspond with the isoelectric point (pI) of the protein, but this is not always the case. The solubility minima and maxima is often complex and may depend on other chemical and physical variables in the crystallization experiment.
Using PEG/pH, PEG/pH 2, or PEG/pH HT one isolates pH, buffer type and relative supersaturation from other chemical and physical variables to screen the effect that pH and buffer type have on the solubility, stability, homogeneity, monodispersity and crystallization of the sample. Varying the pH can alter the protonation state and charge of amino acid residues in the protein, generating different species of the protein for solubility and crystallization screening. The change in pH can have a dramatic effect on inter and intramolecular contacts in the protein and can manipulate how the protein interacts with itself, the surrounding solvent and chemicals in the drop. By screening buffer type and pH in a low ionic strength environment of Polyethylene glycol, PEG/pH simultaneously delivers as a solubility and a crystallization screen for proteins.
Designed as a 96 reagent screen, but offered as two sets of 48 x 10 ml reagents or a single 96 x 1 ml reagent block, PEG/pH, PEG/pH 2, and PEG/pH HT samples Polyethylene glycol 4,000 versus 20 different buffers, at 0.2 M, while sampling pH 3.5 – 9.6.
PEG/pH 1 samples 20% w/v Polyethylene glycol 4,000 versus pH 3.5 – 7.4 in 0.2 M buffer. PEG/pH is supplied in a 48 x 10 ml tube format. PEG/pH is compatible with vapor diffusion, free interface diffusion, and microbatch crystallization methods. For research use only.
PEG/pH 2 samples 20% w/v Polyethylene glycol 4,000 versus pH 6.4 – 9.6 in 0.2 M buffer. PEG/pH 2 is supplied in a 48 x 10 ml tube format. PEG/pH 2 is compatible with vapor diffusion, free interface diffusion, and microbatch crystallization methods. For research use only.
PEG/pH HT samples 20% w/v Polyethylene glycol 4,000 versus pH 3.5 – 9.6 in 0.2 M buffer. PEG/pH HT is supplied in a 96 x 1 ml block format. PEG/pH HT is compatible with vapor diffusion, free interface diffusion, and microbatch crystallization methods. For research use only.

PEG/Ion • PEG/Ion 2 • PEG/Ion HT蛋白结晶试剂盒Hampton Research
Hampton Research蛋白结晶试剂盒
Products > Crystallization Screens > PEG/Ion • PEG/Ion 2 > PEG/Ion • PEG/Ion 2 • PEG/Ion HT
PEG/Ion • PEG/Ion 2 • PEG/Ion HT
Applications
- Primary or secondary, polymer, salt and pH matrix crystallization screen for biological macromolecules
Features
- Developed at Hampton Research
- PEG/Ion is a sparse matrix profile of anions and cations in the presence of monodisperse Polyethylene glycol 3,350 over pH 4.5 – 9.2
- PEG/Ion 2 screens a complete profile of titrated organic acids at varying pH levels (3.7 – 8.8) in the presence of monodisperse PEG 3,350
- PEG/Ion HT combines PEG/Ion and PEG/Ion 2 in a single 96 Deep Well block
Description
PEG/Ion, developed by Hampton Research, is a crystallization screen designed to evaluate monodisperse, high purity Polyethylene glycol 3,350 and 48 unique salts representing a very complete range of anions and cations frequently used in the crystallization of biological macromolecules.
The primary screening variables are PEG, ion type, ionic strength, and pH. More than 60% of the published crystallizations utilized PEG as a primary crystallization reagent and in approximately 50% of those reports, the PEG was combined with an ion as a secondary crystallization reagent. PEG/Ion reagents are formulated without a buffer and are not pH titrated.
PEG/Ion 2 is an extension to the fundamental crystallization strategy in PEG/Ion. PEG/Ion 2 reagents cover the monodisperse, high purity Polyethylene glycol 3,350 and an array of neutralized and pH adjusted organic acids, multivalent ions, a novel Citrate BIS-TRIS propane buffer system and pH (4 – 8.8). The formulation of PEG/Ion 2 was developed at Hampton Research. Each of the 48 reagents in PEG/Ion 2 contains PEG 3,350 as the polymer (precipitant). The concentration of PEG is varied from 12% w/v to 20% w/v depending upon the type and concentration of buffer/salt paired with the polymer. Thirteen of the forty-eight PEG/Ion 2 reagents contain a separate buffer component. The remaining PEG/Ion 2 reagents are buffered by the titrated organic acid salt. Six of these thirteen conditions feature a novel Citric acid BIS-TRIS propane (CBTP) buffer. The CBTP buffer uses Citric acid and BIS-TRIS propane as the acid base pair to create a two component buffer system effective across pH 2.5 to 9.5. The ratio of Citric acid to BIS-TRIS propane determines the solution pH. Thirty-five of the forty-eight PEG/Ion 2 reagents contain a neutralized or pH adjusted organic acid in the presence of the polymer. Neutralized organic acids are highly effective crystallization salts.1 Four PEG/Ion 2 reagents feature polyvalent cations. Two of these reagents contain cation mixes, saving sample by screening six different cations with only two reagents. Tryptone, a casein digest combinatorial library of peptides, is included in PEG/Ion 2. PEG/Ion 2 reagents 1-30, 42, 45-47 are formulated without a buffer and are not pH titrated.
PEG/Ion contains 48 unique reagents, 10 ml each.
PEG/Ion 2 contains 48 unique reagents, 10 ml each.
PEG/Ion HT contains 1 ml of each reagent from PEG/Ion and PEG/Ion 2 in a single Deep Well block format.
Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.
