CloneID: Anti-human PD-1 antibody
Heavy Chain modification: Fc Silent™
Antigen Long Description: The original antibody was generated by immunizing transgenic mice with PD-1.
Buffer Composition: PBS only.
Chimeric Use Statement: This is a reformatted human IgG1 Fc Silent™ antibody, based on the original human IgG1 format, created for improved compatibility with existing reagents, assays and techniques.
Uniprot Accession No.: Q15116
Specificity Statement: The antibody is specific for PD-1. The antibody binds the extracellular region of the human PD-1 protein receptor. PD-1 is a type I membrane protein with 288 amino acids, and is one of the main known immune checkpoints. PD-1 is expressed in activated T lymphocytes, and it binds ligands PD-L1 and PD-L2.
Application Notes (Clone): The specificity of the original format of the antibody was confirmed by ELISA analysis (EC50 = 76 pM). The antibody blocked the binding between PD-1 protein and its ligands PD-L1 and PD-L2 by the receptor ligand binding assay of PD-1 protein. Lymphocyte stimulation assay detected that PD-1 antibody blocked the binding of PD-1 protein to its ligands PD-L1 and PD-L2, thereby releasing its inhibition of T lymphocyte activity (CN106928361A).
