产品介绍 Mouse secreted Programmed Cell Death 1 Ligand 1 (PD-L1)-Fc fusion protein, also known as CD274 and B7 homolog 1 (B7- H1), GenBank Accession No. NM_021893, a.a. 18-238, fused at the C-terminus to the Fc portion of mouse IgG2a and with a Cterminal Avi-tag, expressed in a HEK293 cell expression system. This protein was biotinylated using AviTag™ technology. MW = 54 kDa. Note: this protein runs at an apparent higher molecular weight due to glycosylation.
