The Ansh Labs' Inhibin B ELISA is a quantitative three-step sandwich immunoassay. The Ansh Labs Inhibin B ELISA captures the Beta-B subunit and sandwiches Inhibin B specifically by detecting the alpha subunit. The native human Inhibin B calibrators are optimized and stable after reconstitution up to 14 days at 2-8C, one year at -20C or colder and for up to three freeze-thaw cycles. Wide dynamic range of 14-1300 pg/mL. Sensitive to 7.23 pg/mL. Total 3.5 hour incubation at room temperature. Long shelf life of 24 months. An in-the well sample extraction step using a proprietary detergent and oxidant solution is employed to destroy catalases and proteases present in samples, and to remove binding proteins and potential false positive result causing agents. For Research Use Only within the United States. CE Mark kit available for international purchases.
