Products from BPS Bioscience require a minimum order value above 400€
Encompassing Amino Acids: Heavy Chain: 1-210; Light Chain: 1-214(end)
Applications: Useful as an antagonist to block PD-L1 signaling and binding to PD-1 in biochemical assays.
Assay Conditions: Anti-PD-L1-Biotin (BPS Bioscience #11032) was titrated from 0 to 50 nM with a 2-fold dilution series in presence of 100 nM PD-L1-FLAG (BPS Bioscience #71183) and incubated for 1 hour at RT. Binding was detected with Anti-FLAG-Eu and Streptavidin-APC.
Description: PD-L1 Neutralizing Antibody FAB fragment, recombinant humanized monoclonal, recognizing the extracellular domain of human PD-L1 and blocking the binding of PD-L1 to PD-1. This antibody FAB has been shown to cross-react with mouse PD-L1. No other species have been tested.
