The E2F-1 (Acetyl-Lys120) Antibody Colorimetric Cell-Based ELISA Kit provides a lysate-free, convenient, and high-throughput approach for sensitive detection of E2F-1 (Acetyl-Lys120) Antibody protein expression profile in cells. The kit can be used for measuring the relative amounts of E2F-1 (Acetyl-Lys120) Antibody in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on E2F-1 (Acetyl-Lys120) Antibody.
