Application: Histone H3 (1–21)-GGK(FAM)-NH₂ is a synthetic peptide corresponding to the N-terminal 21 amino acids of human histone H3, modified with a C-terminal GG linker and fluorescein-labeled lysine. The histone H3 N-terminal tail contains key regulatory residues subject to post-translational modifications that influence chromatin structure, gene expression, and protein recruitment. The FAM label enables fluorescence-based detection, visualization, binding studies, and enzymatic assay applications. This fluorescent histone peptide is commonly used in epigenetics research to study histone-modifying enzymes, kinetic analysis, chromatin-associated interactions, reader protein binding, and fluorescence assay development.
