| Purity | >96% 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 1.0×108IU/mg. |
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | Lyophilized from a 0.2μm filtered solution in PBS, pH7.4. |
| Endotoxin | Less than 1EU/μg of rHuIFN-α2b, E. coli 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，所以首次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。所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。

文献和实验Purification of Recombinant Chemokines from E. coli
The majority of chemokines are highly basic, small proteins, with a molecular mass of around 8–10 kDa. Although they do not necessarily have a high level of homology at the primary sequence level, which can be as low as 20
Medium-Throughput Production of Recombinant Human Proteins: Protein Production in E. coli
In Chapter 4 we described the SGC process for generating multiple constructs of truncated versions of each protein using LIC. In this chapter we provide a step-by-step procedure of our E . coli system for test expressing intracellular
Expression of Recombinant Cytochromes c in E. coli
for proper folding and stability. However, significant advances in expression of recombinant cytochromes c have been made during the last decade. It has been shown that a single gene cluster, ccmA–H , is responsible for cytochrome c maturation in Escherichia
