Histone Methylation Quantitative Proteomics by LC-MS/MS

Isolate histones, enrich methylated peptides with modification-specific antibodies, analyze by nanoLC-MS/MS, and quantify changes across treatments.

Key Takeaways

• 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.

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.
