Description
The Quantikine Human CD40 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human CD40 in cell culture supernates, serum, plasma, saliva, urine, and human milk. It contains NS0-expressed recombinant human CD40 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human CD40 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 CD40
