• • Which Antibody Is Optimal for Histone Butyrylation Enrichment?

  Histone acetylation, methylation, and other post-translational modifications have long been central to epigenetics research. Histone butyrylation (Histone Butyrylation, HBu), a novel short-chain fatty acylation modification, is increasingly attracting attention from both academia and the biopharmaceutical industry. Accurate investigation of HBu dynamics is critical for understanding gene regulation, metabolic states, and disease mechanisms. In histone modification analyses, the enrichment step is pivo......

• • How to Isolate Golgi Fractions for Subcellular Proteomics?

  In subcellular proteomics, the Golgi apparatus has long attracted significant attention as a central hub for intracellular protein processing and sorting. Its essential roles in protein glycosylation, vesicular trafficking, and the secretory pathway make it a critical target for elucidating disease mechanisms and identifying potential therapeutic targets. However, precise isolation of the Golgi apparatus remains technically challenging because of its highly dynamic architecture and its extensive physi......
