The Filamin 1 (Phospho-Ser2152) Colorimetric Cell-Based ELISA Kit provides a lysate-free, convenient, and high-throughput approach for sensitive detection of Filamin 1 (Phospho-Ser2152) protein expression profile in cells. The kit can be used for measuring the relative amounts of Filamin 1 (Phospho-Ser2152) in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on Filamin 1 (Phospho-Ser2152).
