描述(Description)
Binding assay by FACS and cell based ELISA.
应用说明(Application)
Human PD-L1, GFP Tag-HEK293 cells stably expressing exogenous human PD-L1 (Programmed cell death 1 ligand 1, CD274, B7-H1, PDCD1L1, PDCD1LG1, AA sequence : Leu 19 - Leu 238, Protein Acc.# : Q9NZQ7-1). At the same time, GFP protein as a marker was expressed in HEK239/hPD-L1 cells for screening positive cells by FACS.

活性(Bioactivity)
Flow Cytometry assay shows that PE-Labeled Human PD-1, Fc Tag, His Tag (recommended for neutralizing assay) (Cat. No. PD1-HP2F2) can bind to 293T cells overexpressing human PD-L1. 1 μl stock solution per million cells (Routinely tested).
Protocol
FACS analysis shows that the binding of PE-Labeled Human PD-1, Fc Tag, His Tag (recommended for neutralizing assay) (Cat. No. PD1-HP2F2) to 293T overexpressing PD-L1 was inhibited by increasing concentration of neutralizing anti- human PD-L1 antibody. The IC50 is 0.29 μg/ml (Routinely tested).
