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 Interferons. All three IFN-lambdas uses a distinct receptor system composed of an IFN-lambdaR1 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. Recombinant murine IFN-lambda2 is a 19.8 kDa protein containing 175 amino acid residues.
Mouse Ifnl2 expressed in E.coli
CAT# CSC-CTK0676-20 (20 μg); CAT# CSC-CTK0676-100 (100 μg)
Greater than 95% as determined by SDS-PAGE and HPLC analysis.
Determined by its ability to activate STAT following receptor-ligand interaction.
Less than 1 EU/μg.
Lyophilized (freeze-dried), sterile powder. Lyophilized with no additives.
Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0,1 - 1,0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted rMu IFN-lambda-2 should be used immediately or stored long-term in undiluted working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
