构象分析ELISA试剂盒 |
此试剂盒可用于生物仿制药和投入市场的单克隆抗体之间的3-D构象比较和高级结构鉴定,这项新技术提供了一种在分子水平上对生物仿制药构象可比性的高灵敏度、系统性和稳定检测。 |
◆适用领域 ● 单克隆抗体 ● 药物偶联物 ● 细胞系筛选 ● 工艺过程开发 ● 剂型开发 ● 可比性研究 ● 产品特性分析 |
|
◆作用原理 该试剂盒采用多于三十个多克隆抗体覆盖一个单克隆抗体,来检测表面抗原表位的分布,系统性更强,灵敏度更高,提供用于生物仿制药和单克隆抗体高级结构可比性研究的独特方法。 采用抗生物体内全长蛋白序列的抗体,每个抗体都能特异性识别相应的多肽抗原。当多肽是正确折叠的全长蛋白时,其抗原性表现在3D结构中,只有有限数量的抗体会应答。 抗体结合部位可作为判定生物仿制药多肽正确折叠的指纹指标,如果生物仿制药正确折叠和糖基化,指纹便会符合。如果生物仿制药没有正确折叠,高级结构发生不同程度的改变时,原本被掩盖的抗原表位暴露出来,导致抗体对其识别的信号增强。 |
◆主要特点
● 生物仿制药和单克隆抗体之间的高级结构可比性的独特检测。
● 可检测到少量的构象杂质,含量低至0.1%。
● 支持后续的生物测定和糖基化分析。

Colourimetric method for the determination of β-Glucan in
cereal grains, feed, foodstuffs, beverages and other materials
Principle:
(lichenase)
(1) β-Glucan + H2O → β-gluco-oligosaccharides
(β-glucosidase)
(2) β-Gluco-oligosaccharides + H2O → D-glucose
(glucose oxidase)
(3) D-Glucose + H2O + O2 → D-gluconate + H2O2
(peroxidase)
(4) 2H2O2 + p-hydroxybenzoic acid + 4-aminoantipyrine →
quinoneimine + 4H2O
Kit size: 100 assays
Method: Spectrophotometric at 510 nm
Total assay time: ~ 100 min
Detection limit: 0.5-100% of sample weight
Application examples:
Oats, barley, malt, wort, beer, food and other materials
Method recognition:
AOAC (Method 995.16), AACC (Method 32-23.01), EBC (Methods
3.10.1, 4.16.1 and 8.13.1), ICC (Standard No. 166), RACI (Standard
Method) and CODEX (Type II Method)
Advantages
- Very cost effective
- All reagents stable for > 2 years as supplied
- Only enzymatic kit available
- Very specific
- Simple format
- Mega-Calc™ software tool is available from our website for hassle-free raw data processing
- Standard included
Q1. Should the pH of the sample be adjusted even for samples in acidic media?
The pH of the assay solution after the sample is added should be the same as that of the assay buffer that is supplied with the kit.
Low sample volumes (e.g. 0.1 mL) are not likely to affect the pH of the assay solution and therefore may not require pH adjustment.
Samples above 0.1 mL are more likely to affect the pH of the assay solution and therefore the pH of these samples should be adjusted as described in the data booklet, prior to addition to the assay.
Q2. There is an issue with the performance of the kit; the results are not as expected.
If you suspect that the Megazyme test kit is not performing as expected such that expected results are not obtained please do the following:
- Ensure that you have tested the standard sample that is supplied with the Megazyme test kit.
- Send the results of the kit standard, blank samples and the results obtained for your sample, in the relevant MegaCalc spreadsheet (if available) to Megazyme (cs@megazyme.com). Where available the relevant MegaCalc spreadsheet can be downloaded from where the product appears on the Megazyme website.
- State the kit lot number being used (this is found on the outside of the kit box).
- State which assay format was used (refer to the relevant page in the kit booklet if necessary).
- State exact details of any modifications to the standard procedure that is provided by Megazyme.
- State the sample type and describe the sample preparation steps if applicable.
Q3. We have measured the molecular weight of beta-glucan originating from barley ordered from your company. Can you please tell us which method have you used for measuring molecular weight?
The MW’s were determined by Multiangle laser light scattering technique.
Q4. I have purchased barley beta-glucan (lot 30108) and carob galactomannan low viscosity (lot 30702) and would like to know what else there might be in these substrates.
Barley beta-glucan lot 30108 would contain about 3-4% arabinoxylan (this was produced in 1993). Material supplied post 1995 contains < 0.5% arabinoxylan. Carob galactomannan is quite pure (> 96%).
Q5. Although not specified on the beta-glucan data sheet, is the ratio of 1-3 to 1-4 bonds measured? If so, what is the ratio and would you expect it to remain standardised over a number of different batches?
The content of 1,3 bonds in barley beta-glucan is about 32% (from literature). We would not expect this to change much (if at all) over different batches.
Q6. Both substrates; barley beta-glucan and wheat arabinoxylan, are standardised to a specific viscosity, e.g. 23-24 cSt. Are the substrates adjusted to give this viscosity?
The substrates are enzymically treated to yield the required viscosity (20 ~ 30 cSt). Modification of the viscosity of beta-glucan is required for IOB viscometric malt beta-glucanase test (which works well).
Q7. We are setting up reducing-sugar assays for both beta-glucanase and xylanase from different fungal origins. Which barley beta-glucan do you recommend for the glucanase assay.
For glucanase assay we recommend the medium viscosity beta-glucan. We now offer low, medium and high viscosity wheat arabinoxylans, and we think that the low viscosity material will be best (easiest) to use in the reducing-sugar assay.
