Products from BPS Bioscience require a minimum order value above 400€
Encompassing Amino Acids: 25-167
Applications: Useful for studying protein binding and screening small molecular inhibitors
Assay Conditions: 10 nM PD-L1, Biotinlabeled(BPS Cat. #71105) was mixed withvarying amounts of PD-1, FLAG-tag (BPSCat. #71198) in PD-1 Assay Buffer for 1 hrat RT. FLAG-acceptor beads (left) or Nickel-acceptorbeads (right) were added andincubated for 30 min at RT followed bystreptavidin-conjugated donor beads for 30min at RT. Alpha counts were read.
Description: Human secreted programmed cell death 1 (PD-1), also known as PDCD1, SLEB2, CD279 and HPD-L, GenBank Accession No. NM_005018, a.a. 25-167, with C-terminal FLAG-Avi-His-tags, MW=20 kDa, expressed in a HEK293 cell expression system. This protein runs at a higher M.W. by SDS-PAGE due to glycosylation.
