HEK-293

Human

Detects human PD-L1. This non-therapeutic antibody uses the same sequence as the therapeutic antibody Durvalumab.

This recombinant antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

RUO Durvalumab biosimilar is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2. It is an IgG1 kappa immunoglobulin with an approximate molecular weight of 149 kDa.
