Histone H4 (1-21) R3(Me1)-GGK(Biot)

This peptide is histone H4 amino acid residues 1 to 21. It is monomethylated at Arg3, with an acetylated N-terminus and C-terminal GG linker, followed by a biotinylated Lys. Methylation of histone H4 at Arg3 is an important step in transcriptional activation and allows for subsequent acetylation of H4 tails by p300. Provided at >90% peptide purity, this peptide was dissolved in distilled water at 1 mg/ml and re-lyophilized to powder form.'
