Recombinant Human IFN-β

제품 설명

Proteins of this family play an important role in inducing non-specific resistance against a broad range of viral infections.  They also affect cell proliferation and modulate immune responses.  Produced by peripheral blood leukocytes and lymphoblastoid cells, IFN-α is an acid-stable molecule that signals through IFN-α/βR, which is also used by IFN-β.  Both IFNs have similar anti-viral activity and regulate expression of MHC class I antigens.  IFN-α contains four highly conserved cysteine residues that form two disulfide bonds, one of which is necessary for biological activity.  PeproTech’s Recombinant Human IFN-β is a 20.0 kDa protein containing 166 amino acid residues. Due to glycosylation, IFN-β has an approximate MW of 22.3 kDa based on SDS-PAGE gel and Mass Spectrometry.
