CD273 [PD-L2] (human)-muIg Fusion Protein, preservative free

CD273 (B7-DC, PCDL-2, Programmed cell death ligand 2, Butyrophilin-like protein) is a type I surface molecule with homology to CD80, CD86, CD274. It is expressed primarily by Dendritic cells.and provides a stimulatory signal to CD279 (PD-1, Programmed Death molecule) which serves an important immunoregulatory role by down regulating T cell response. CD273 binds to CD279(PD-1) with a 2- 6 fold higher affinity than CD274. Recombinant CD273-muIg binds to recombinant CD279 in EIA. Predicted monomeric (non glycosylated) molecular weight: 49 kd. The molecule is dimeric and runs at ~135 kd in SDS-PAGE under native conditions, and ~74 kd reduced.
