Elite™ cAMP 384-Well ELISA Kit provides a sensitive method for detecting adenylate cyclase activity in biochemical or cell-based assay system. Compared to other cAMP ELISA kits, our kit eliminates the tedious acetylation step. The kit uses Elite™ Red as a fluorimetric substrate to quantify the HRP activity. The high sensitivity (for as low as 0.1 nM) makes it superior to any other known colorimetric-based or fluorescence-based kits in the market.
