Description
BP000083-GD25: Recombinant Human IFNa 2b Protein
Background
At least 23 different variants of Interferon-alpha are known. The individual proteins have molecular masses between 19-26 kDa and consist of proteins with lengths of 156-166 and 172 amino acids. All IFN-alpha 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 carboxyl-terminal end.

Source: E. coli-derived.
The specific activity as determined by a viral resistance assay using VSV-WISH cells was found to be 1.0 x 10^8 IU/ mg.
Predicted molecular mass: 19,400 Daltons.
Purity: > 95% by RP-HPLC and reducing SDS-PAGE.
Endotoxin: < 0.1 ng/ug (1 EU/ug). Formulation: Lyophilized from a 0.2 um filtered solution of 20 mM PB, 150 mM NaCl, pH 7.2. Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 ug/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. Shipping: The product is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below. Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70°C as supplied. 1 month, 2 to 8°C under sterile conditions after reconstitution. 3 months, -20 to -70°C under sterile conditions after reconstitution.
