The Adrenergic Receptor alpha-2C Colorimetric Cell-Based ELISA provides a lysate-free, convenient, and high-throughput approach for sensitive detection of AdrenergicReceptoralpha-2C protein expression profile in cells. The kit can be used for measuring the relative amounts of AdrenergicReceptoralpha-2C in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on AdrenergicReceptoralpha-2C.
