Human PD-L1 / B7-H1 (19-134) Protein, His Tag (recommended for biopanning) (MALS verified)

PD-L1, CD274, B7-H1, PDCD1L1, PDCD1LG1

Human PD-L1 (19-134), His Tag (PD1-H52H3) is expressed from human 293 cells (HEK293). It contains AA Phe 19 - Tyr 134 (Accession # Q9NZQ7-1).

PD1-H52H3 works best for experiments that test the binding between PD-L1 and candidate antibodies, such as biopanning and other relevant assays.

This product is NOT suitable for testing PD1-PDL1 binding. For this type of application, we strongly recommend you to choose PD1-H82F3 as an alternative.
