The Quantikine? Human/Cynomolgus Monkey B7-H1/PD-L1 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human/cynomolgus monkey B7-H1 in cell culture supernates, cell lysates, serum, plasma, and urine. It contains HEK293-expressed recombinant human B7-H1/PD-L1 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human/cynomolgus monkey B7-H1/PD-L1 showed linear curves that were parallel to the standard curves obtained using the Quantikine? kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human/cynomolgus monkey B7-H1/PD-L1. Range: 25.00 - 1600 pg/mL. Sensitivity: 4.52 pg/mL. Time: 4.5 hours
