Soluble human PD-L1 fused to an IgG1 Fc domain
hPD-L1-Fc is a soluble human PD-L1 (CD274) fusion protein generated by fusing the N-terminal extracellular domain of human PD-L1 (aa 19-237) to the N-terminus of an engineered human IgG1 Fc domain with a 2 amino acid linker.
hPD-L1-Fc has an apparent molecular weight of ~66 kDa on an SDS‑PAGE gel.
hPD‑L1‑Fc is expressed in CHO cells and purified by protein G affinity chromatography.
Applications: Flow cytometry, protein-protein interaction studies, T cell activation blocking (binding to hPD-1 expressed on T cells).

Programmed cell death ligand 1 (PD-L1), also known as B7 homolog 1 (B7-H1) and cluster of differentiation 274 (CD274), is a member of the B7 family of immunoregulatory proteins .
It is a transmembrane protein over‑expressed on tumor cells and tumor infiltrating immune cells, such as macrophages.
PD-L1 binds to programmed cell death protein 1 (PD-1; also known as CD279) on cytotoxic T cells, inhibiting the antitumor immune response [2,3].
