Product Specific Information
For reconstitution, add 100 µL of distilled water to achieve a final antibody concentration of approximately 1 mg/mL.
For conjugation experiments, it is recommended to perform an additional desalting step (e.g., Zeba Spin Desalting Columns, 7K MWCO, 0.5 mL, Product #89882).
Target Information
Programmed death receptor ligand 1 (PD-L1, also known as B7-H1) is a member of the B7 family. It binds to its receptor PD-1, which negatively regulates T-cell receptor (TCR) signaling. Upon binding, PD-L1 decreases TCR-mediated proliferation and cytokine production. PD-L1 expression is abundant in many murine and human cancers and can be further upregulated by IFN-gamma stimulation. Therefore, PD-L1 plays an important role in tumor immune evasion.
