PD-L1 Antibodies
Programmed-death ligand 1 (PD-L1) is a 33 kDa type I glycoprotein belonging to the B7 protein family that functions as an immune checkpoint. PD-L1 is typically expressed by tumor and antigen presenting cells and binds the receptor programmed-death 1 (PD-1). During homeostasis the PD-L1/PD-1 signaling axis helps prevent autoimmunity, but in the tumor microenvironment it inhibits T cell activity and promotes tumor cell escape. We offer PD-L1 antibodies that have been featured in 70+ publications, including 4- and 5-star customer reviewed antibodies. Browse our catalog of rabbit recombinant monoclonal, monoclonal, polyclonal, and PD-L1-conjugated antibodies. Validated research applications for these PD-L1-antibodies include Blocking/Neutralizing, CyTOF-Ready, ELISA, Flow Cytometry, ICC, Immunofluorescence, IHC-Frozen, IHC-Paraffin, Knockdown, Simple Western, and Western Blot.
