A number of ELISA Kits are available that target INF-alpha, an alias of the protein, interferon lambda 3. The human protein, encoded by the gene IFNL3, is a member of the Lambda interferon family. The protein's cellular localization is indicated to be secreted. Additional synonyms or past names for this protein may include: IFN-lambda-3, IFN-lambda-4, IL-28B, IL-28C, IL28B, IL28C. Homology is conserved in other species, such as Mouse, Rat.
