产品详细信息
Recombinant Human IFN-β
产品编号:
AF-300-02B
别名:
Leukocyte interferon, B cell interferon, Type I interferon
描述:
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, IFNα is an acid
stable molecule that signals through IFNα/βR, which is also used by
IFNβ. Both IFNs have similar anti-viral activity and regulate
expression of MHC class I antigens. IFNα contains four highly conserved
cysteine residues which form two disulfide bonds, one of which is
necessary for biological activity. Recombinant human IFNβ is an 20.0
kDa protein containing 166 amino acid residues. Manufactured using all non-animal reagents.
