Applications of Biotinylated Histone Peptides

The versatility of biotinylated histone peptides makes them invaluable tools across a spectrum of epigenetic research. Their primary utility lies in their application in peptide pull-down and/or binding assays. By immobilizing biotinylated histone peptides onto avidin or streptavidin-coated surfaces, researchers can efficiently isolate and identify proteins that specifically interact with particular histone modifications. This is crucial for discovering novel protein partners involved in epigenetic regulation. For instance, a biotinylated histone H3 peptide representing a specific methylation state can be used to pull down proteins that recognize and bind to that modification, shedding light on the downstream effects of that particular PTM.

Furthermore, biotinylated histone peptides are instrumental in developing and validating antibodies. They can serve as immunogens for antibody production or as positive controls in Western blot or ELISA assays to confirm antibody specificity towards modified histone epitopes.Biotinylated HistoneH3PeptideSubstrate ... *US Pricing only.
