The Quantikine Human VAP-1 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human VAP-1 in cell culture supernates, serum, and plasma. It contains Sf 21-expressed recombinant human VAP-1 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human VAP-1 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 VAP-1. Range: 0.78 - 50 ng/mL. Sensitivity: 0.077 ng/mL. Time: 4.5 hours
