Human secreted Programmed Cell Death 1 Ligand 1 (PD-L1)-Fc fusion protein, also known as CD274 and B7 homolog 1 (B7-H1) with a Y123A mutation, GenBank Accession No. NM_014143, amino acids 19-239, fused at the C-terminus with the Fc portion of human IgG1, with C-terminal Avi-tag™ expressed in a HEK293 cell expression system. MW = 54 kDa. This protein runs at a higher MW by SDS-PAGE due to glycosylation.

CD274, B7 homolog 1, B7-H1

8 mM Phosphate, pH 7.4, 110 mM NaCl, 2.2 mM KCl, and 20% glycerol

At least 6 months at –80°C. Avoid freeze/thaw cycles. Protein may be diluted to ≥ 100 µg/ml in PBS + glycerol and stored at -80°C.

Useful for the study of protein-protein interaction, epitope mapping, and in vitro and in vivo protein function.
