Compare the performance of the new estradiol ELISA kit developed by Cayman’s scientists with its predecessor

Acritical shortage of the antibody used in Estradiol ELISA Kit (Item No. 582251) prompted the need for a replacement Estradiol ELISA Kit (Item No. 501890). Cayman’s scientists developed a new antiserum with less cross reactivity compared to the previous kit and changed the sample preparation/extraction protocol to a simpler and less hazardous format that provides improved specificity. Synthetic 17β-estradiol and samples of human plasma were tested side by side in both kits to compare performance.
