描述
BP000082-GD27: Recombinant Human IFNa 2a 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.
BP000082-GD27: Recombinant Human IFN alpha 2a (IFNA2) Protein
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: 19,241 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.
