Recombinant Human IFN-λ1



Catalog Number : 300-02L

Description

IFN λ-1,-2, and -3 (also known as IL-29, IL-28A and IL-28B respectively) are distantly related to the IL-10 family and Interferons. All three IFN-λs use a distinct receptor system composed of an IFN-λR1 subunit (also called CRF2-12) and IL-10R2 subunit (also called CRF2-14). Signaling through this receptor system induces antiviral defense similar but distinct than the type I Interferons. (Kotenko, SV. et al. Nat Immunology 2003 [1] p. 69-77). Recombinant human IFN-λ 1 is a 19.8 kDa protein containing 178 amino acid residues.
