Hintergrund: B7-H1, also known as PD-L1 and CD274, is an approximately 65 kDa transmembrane glycoprotein in the B7 family of immune regulatory molecules. PD-L1 has been identified as the ligand for the immunoinhibitory receptor programmed death-1(PD1/PDCD1) and has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance.

Molekulargewicht: 26 kDa. Due to glycosylation, the protein migrates to 35-45 kDa based on Tris-Bis PAGE result.

UniProt: G7PSE7
