Schematic procedure for using the EpiQuik In Situ Histone H3 Phosphorylation (Ser10) Assay Kit.
Log-phase MCF-7 cells were serum-starved overnight, and serum was added back for 30 minutes followed by treatment with Calyculin A (CL-A, 0.2 μM for 30 minutes). The level of H3 phosphorylation at ser10 was measured with this kit.
