Histone Methylation Quantitative Proteomics by LC-MS/MS
-
Methylation regulates gene expression and cell fate.
-
Antibody enrichment boosts low-abundance methyl marks.
-
High-resolution MS resolves isobaric forms.
-
TMT or label-free quant compares conditions.
Isolate histones, enrich methylated peptides with modification-specific antibodies, analyze by nanoLC-MS/MS, and quantify changes across treatments.

FAQ
1. Can one run detect all methyl states?
Enrichment and MS settings must match target marks (Kme1/2/3, Rme).
2. Why histone-specific prep?
Acid extraction reduces non-histone peptide dominance.
Conclusion
Quantitative histone methylation proteomics reveals epigenetic programs at site resolution.
