Histone H4 K5Ac Peptide Description: A synthetic peptide derived from human histone H4, amino acids 1-23, acetylated at lysine 5. The alpha-amino group on the N-terminus is acetylated, with a C-terminal PEG spacer containing a biotin moiety.
Histone H4 K5Ac Peptide Formulation: 50 µg of lyophilized powder.
Purity: >99% as judged by HPLC and mass spectrometry.
Storage and Stability: Lyophilized peptides are stable for 2 years at -20°C from date of shipment. Peptides in solution are stable for 6 months at -20°C. Reconstitute with sterile distilled water and aliquot to avoid repeated freezing and thawing.
Quality Control: Peptide purified by reversed-phase HPLC and analyzed using MALD-TOF mass spectrometry and analytical RP-HPLC.
Mass Spec Data: MALDI-TOF mass spectrometry was used to analyze histone H4 K5Ac peptide for identity and homogeneity.
