BP000082-C025: Recombinant Human Interferon-alpha 2a (IFNα 2a) Protein
Source: E. coli-derived.
The specific activity as determined in a viral resistance assay using VSV-WISH cells was found to be greater than 1.0 x 10^8 IU/ mg.
Purity: > 95% by RP-HPLC and reducing SDS-PAGE.
Endotoxin: < 0.1 ng/ug (1 EU/ug).BP000082-CYT-093: Recombinant Human Interferon-alpha 2a (IFNα 2a) Protein, HEK Protein

The specific activity was determined by a quantitative gene report bioassay using human Type I interferon-sensitive cells. Compared with bacterial derived recombinant IFN-a 2a, assayed in the same conditions, plant derived IFN-alpha 2a showed 6.1 x 10^8 Units/mg in reference to a viral resistance assay using bovine kidney MDBK cells.
Purity: > 99% by SDS-PAGE and RP-HPLC.
