Recombinant Anti-CD274 Biparatopic Antibody, Tandem scFv
CAT#: VS-0525-YC202
The Recombinant Anti-CD274 Biparatopic Antibody, Tandem scFv was designed as a biparatopic antibody (bpAb) with tandem scFv arms, this construct binds two distinct epitopes on CD274 (PD-L1) with high affinity. One epitope is constituted by the C, F, and G strands, the CC' loop, and the N-terminal region of PD-L1. The other epitope is formed by the CC'FG antiparallel β-sheet and the BC, CC', C''C'', and FG loops.

Target
- Introduction
- This gene encodes an immune inhibitory receptor ligand that is expressed by hematopoietic and non-hematopoietic cells, such as T cells and B cells and various types of tumor cells. The encoded protein is a type I transmembrane protein that has immunoglobulin V-like and C-like domains. Interaction of this ligand with its receptor inhibits T-cell activation and cytokine production. During infection or inflammation of normal tissue, this interaction is important for preventing autoimmunity by maintaining homeostasis of the immune response. In tumor microenvironments, this interaction provides an immune escape for tumor cells through cytotoxic T-cell inactivation. Expression of this gene in tumor cells is considered to be prognostic in many types of human malignancies, including colon cancer and renal cell carcinoma. Alternative splicing results in multiple transcript variants.
