Synonyms :

IL-29

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-lambdas 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.

E.coli

Stability :

The lyophilized protein is stable for at least 2 years from date of receipt at -20⁰C. Reconstituted IFN-λ 1 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20⁰C. Avoid repeated freeze/thaw cycles.

Purity :

Greater than 98% by SDS-PAGE gel and HPLC analyses.

Endotoxin Level :

Endotoxin level is less than 0.1 ng per µg (1EU/µg).

Biological Activity :

Recombinant human IFN-lambda 1 induces phosphorylation of STAT2.
