Histone Phosphorylation

Validated antibodies and ELISA kits for measuring histone phosphorylation marks

When you need to measure histone phosphorylation marks (H3S10ph mitosis, gamma-H2AX DNA damage, H3T3ph mitotic chromatin), this section covers antibodies, ELISA kits, and substrate reagents. Phospho-antibody specificity is notorious for cross-reactivity; validated antibodies matter.

Pick by mark and format.

  1. Mark. H3S10ph for mitosis. Gamma-H2AX for DNA double-strand breaks. H3T3ph for mitotic chromatin states.
  2. Format. Western blot, ELISA, immunofluorescence, flow cytometry each have a role.
  3. Antibody validation. Phospho-antibody specificity varies. Validated antibodies essential.
  4. DNA damage assays. Gamma-H2AX immunofluorescence remains gold standard for cleanest per-cell resolution. ELISA-based bulk quantification has lower resolution.
  5. Multiplex. For combined PTM panels match conjugate compatibility.

EpigenTek leads with phospho-histone ELISA kits and antibody panels.
