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.
Immunogen Region
19-239
Tag
C-terminal Avi-tag
Formulation
8 mM Na Phosphate pH 7.4, 110 mM NaCl, 2.2 mM KCl and 20% glycerol
