Human secreted programmed cell death 1 (PD-1)-Fc fusion protein, also known as, PDCD1, SLEB2, CD279 and HPD-L, GenBank Accession No. NM_005018, a.a 25-167, fused at the Cterminus to the Fc portion of human IgG1, expressed in a HEK293 cell expression system. This protein runs at a higher M.W. by SDS-PAGE due to glycosylation. The protein was randomly labeled with RPE on accessible lysine residues.
Immunogen Region
25-167
Tag
Fc Fusion (Human IgG1)
Formulation
8 mM Na phosphate pH 7.4,110 mM NaCl, 2.2 mM KCl and 20% glycerol
Species
Human
Application
Useful for labeling PD-L1- expressing cells for flow cytometry, immunofluorescence, and live cell imaging. For FACS analysis on human cells expressing PD-1, we recommend preclearing by using a non-specific antibody at 10 ug/ml to remove any non-specific binding, followed by PE labeled PD-1 fusion protein at 20 ug/ml.
Notes
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.
