Vitamin D BP ELISA from R&D Systems, a Bio-Techne Brand

The Quantikine® Human Vitamin D BP immunoassay is a 3.5 hour sandwich-type solid phase ELISA designed to measure human Vitamin D BP in cell culture supernates, serum, plasma, and urine. It contains HEK293-expressed recombinant human Vitamin D BP and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Vitamin D BP 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 natural human Vitamin D BP. Read more about the Vitamin D BP specificity in this White Paper
