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.
Immunogen Region

Tag
C-terminal FLAG-Avi- His-tag
Formulation
8 mM phosphate pH 7.4,110 mM NaCl, 2.2 mM KCl, and 20%glycerol
Species
Human
Application
Useful for studying protein binding and screening small molecular inhibitors
Notes
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.
This protein runs at ahigher M.W. by SDS-PAGE due toglycosylation. The aggregation state of this product has been confirmed to be<10%. Avoid freeze/thaw cycles. Protein may be diluted to>=100 ug/ml in PBS + glycerol and stored at -80°C.
