IFN Lambda 1, 2, and 3 (also known as IL-29, IL-28A and IL-28B respectively) are distantly related to the IL-10 family and the interferons.  All three IFN-lambdas use a distinct receptor system composed of an IFN-Lambda R1 subunit (also called CRF2-12) and IL-10R2 subunit (also called CRF2-14).  Signaling through this receptor system induces antiviral defenses similar to, but distinct from, that of type I interferons.  Recombinant human IFN-Lambda 1 is a 19.8 kDa protein containing 178 amino acid residues.

Determined by its ability to activate STAT phosphorylation in an ISRE Luciferase Reporter Assay using human colon carcinoma COLO205 cells. The expected ED50 is 0.2-0.5 ng/ml.
