This recombinant Human PDL1 protein is made from HEK293 cells. It is secreted with the sequence of Human PDL1 (amino acids 19-239) fused with a mouse IgG1 Fc tag at the C-terminus.

Also known as: PD-L1, PDCD1 ligand 1, programmed death ligand 1, cluster of differentiation 274 (CD274), B7 homolog 1 (B7-H1).



Programmed Death Ligand 1 (PDL1) is a member of the growing B7 family of immune proteins that provide
signals for both stimulating and inhibiting T cell activation. It is a 40kDa type 1 transmembrane protein that
has been speculated to play a major role in suppressing the immune system during particular events such
as pregnancy, tissue allografts, autoimmune disease and other disease states such as hepatitis. PD-L1
binds to its receptor, PD-1, found on activated T cells, B cells, and myeloid cells, to modulate activation or
