PD-1 is a critical immune checkpoint receptor whose extracellular domain mediates interactions with PD-L1 and therapeutic antibodies targeting the PD-1/PD-L1 axis. This recombinant human PD-1 construct covers the ligand-binding extracellular domain (aa 25–167) and is expressed in mammalian cells to preserve native glycosylation and conformational integrity essential for accurate binding studies. Functional ELISA validation demonstrates robust activity, with EC50 values of 6.087–7.854 ng/ml against an anti-PD-1 recombinant antibody and 9.713–12.39 ng/ml against Nivolumab, confirming suitability for competitive blocking antibody screening, therapeutic antibody epitope mapping, and affinity characterization by SPR or BLI. The protein provides a suitable basis for immune checkpoint drug discovery assays and positive binding controls, supported by purity exceeding 95% (SDS-PAGE) and endotoxin levels below 1.0 EU/μg that satisfy criteria typical for sensitive cell-based functional studies.

Review: I used CSB-MP619964HU1 product for enzyme-linked immunosorbent assay, the EC50 was 2.410-5.471ng/ml, and the protein activity was good. Subsequently, it was coated on the plate for monoclonal antibody screening and got a good linear curve. It\'s a stable protein with good repeatability and easy to use, and I will purchase other products!
