Human Interferon-alpha 2b, Saccharomyces protein

SKU: orb80040

Description

Interferon-alpha 2b Human Recombinant produced in yeast is a single, glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of approximately 19 kDa.The Interferon-alpha 2b gene was obtained from human leukocytes.The IFN-a 2b is purified by proprietary chromatographic techniques.

Images & Validation

• Tested Applications: FA, HPLC, SDS-PAGE
• Application Notes:
  < strong>Experiment Notes: Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.924 as the extinction coefficient for 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using calibrated solution of IFN-a 2b as Reference Standard.
