简单介绍
Recombinant Human IFN-α2b, Yeast由于有些塑料管壁对某些蛋白有较强的吸附作用,溶液中的蛋白很容易粘附在管壁上,并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein,如0.1% BSA等)的主要作用是预先封闭塑料管壁上的蛋白结合位点���使细胞因子或重组蛋白不会粘附于管壁。Recombinant Human IFN-α2b, Yeast所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。

IFNA2; IFNA2b; alpha-2a interferon; IFNA; IFN-alpha-2; IFN-alphaA; INFA2; interferon alpha 2b; interferon alpha A; interferon alpha-2; Interferon alpha-A; interferon, alpha 2; LeIF A; MGC125764; MGC125765

Purity

>98% by SDS-PAGE and HPLC analyses.

Biological Activity

Fully biologically active when compared to standard. The specific activity determined by an anti-viral assay is no less than 1.6 ×108IU/mg.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation

Lyophilized from a 0.2μm filtered solution in PBS, pH7.4, with 0.02% Tween-20.

Endotoxin

Less than 0.1EU/μg of rHuIFN-α2b, Yeast as determined by LAL method.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at -20. Further dilutions should be made in appropriate buffered solutions.

Background

IFN-αs are proteins secreted by leukocyte. They are mainly involved in innate immune response against viral infection. The IFN-α family has 13 subtypes and 23 different variants. The individual proteins have molecular masses between 19-26kDa and consist of proteins with lengths of 156-166 and 172 amino acids. All IFN-α subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-alpha subtypes differ in their sequences at only one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end.

保存条件:
       -20℃或更低温度保存,至少一年有效。由于蛋白的每次冻融均会引起部分失活,所以**配制成相应浓度的储存液后(请根据产品简介中Reconstitution一栏的信息配制储存液),须分装后-20℃或更低温度冻存,以避免反复冻融。
注意事项:
       由于有些塑料管壁对某些蛋白有较强的吸附作用,溶液中的蛋白很容易粘附在管壁上,并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein,如0.1% BSA)的主要作用是预先封闭塑料管壁上的蛋白结合位点,使细胞因子或重组蛋白不会粘附于管壁。所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。
       本产品**于专业人员的科学研究用,不得用于临床诊断或**,不得用于食品或药品,不得存放于普通住宅内。
       为了您的**和健康,请穿实验服并戴一次性手套操作。
