Device immunohistochemistry assay, antibody, programmed death-ligand 1
Definition The programmed death-ligand 1 (PD-L1) antibody is a qualitative immunohistochemical antibody intended to identify PD-L1 protein expression in human clinical tissue specimens. The PD-L1 antibody is indicated as an aid in identifying patients eligible for treatment with specific FDA approved therapeutic drugs or to assess PD-L1 expression level in patients who may respond particularly well to specific FDA approved therapeutic drugs.
Physical State The device includes a monoclonal primary antibody and accessory reagents, including secondary antibodies, buffers, substrates, and counterstains. The device may be intended for manual or automated staining methods.
Technical Method The test uses a primary monoclonal antibody to detect the presence of expressed antigen protein in fixed tissue specimens. Antibody-antigen complexes are visualized using an enzyme conjugated primary or secondary antibody to catalyze a color-producing reaction.
