Interleukin 29 (IL-29), also known as IFNl1, is a type III interferon produced by virally infected cells. It is thought to play an important role in host defenses against multiple microbes and shares homology with IL-28.

Source:
Recombinant protein corresponding to 179aa human IL-29 expressed in E.coli.

Molecular Weight:
~19.9kD

Endotoxin:
1EU/ug (LAL)

Biological Activity:
The activity is determined by an anti-viral assay of EMC infected HepG2 cells and is typically 1-5ng/ml.
