The Quantikine Human Angiopoietin-1 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Angiopoietin-1 in cell culture supernates, serum, plasma, saliva, and human milk. It contains NS0-expressed recombinant human Angiopoietin-1 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Angiopoietin-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 Angiopoietin-1. Range: 62.50 - 4000 pg/mL. Sensitivity: 10.3 pg/mL. Time: 4.5 hours
