Product Overview
Tag | N/A |
Host Species | Human |
Synonym | Interferon alpha 2b, IFNA, INFA2, IFN-? 2b, MGC125764, MGC125765. |
Background | IFN-alpha is expressed by macrophages and has antiviral activities. Interferon stimulates the production of two 56: protein kinase and an oligoadenylate synthetase. |
Description | Interferon-alpha 2b Human Recombinant expressed in yeast is a single, glycosylated, polypeptide chain containing 165a.a. and having a molecular weight of approximately 19 kDa.The Interferon-alpha 2b gene was obtained from human leukocytes.The IFN-a 2b is purified by unique purification methods. |
Source | Saccharomyces cerevisiae |
AA Sequence | The sequence of the first five N-terminalaa was determined and was found to be Cys-Asp-Leu-Pro-Gln. |
Purity | >98.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
Endotoxin | <1.0 EU per μg by the LAL method. |
Bioactivity | The specific activity as determined in a viral resistance assay was found to be no less than 300,000,000IU/mg. |
Formulation | Lyophilized from a 0.2μm filtered concentrated (1mg/ml) solution in PBS, pH-7.4. |
Stability | Recombinant protein is stable for 12 months at -70°C |
Usage | For Research Use Only |
Storage | Lyophilized glycosilated IFN-a 2b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFN-alpha 2b should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
