Background
Cluster of differentiation 80 (also CD80 and B7-1) is a protein found on dendritic cells, activated B cells and monocytes that provides a costimulatory signal necessary for T cell activation and survival. It is the ligand for two different proteins on the T cell surface: CD28 and CTLA-4.
Description
Recombinant Cynomolgus B7-1/CD80 Protein is expressed from Expi293 with His tag at the C-terminal. It contains Val35-Asn242.
