What [Lys(Ac)27]-Histone 3 (21-44)-GK(Biotin); H3K27(Ac), biotin-labeled is studied for

  • HAT / HDAC / HMT / KDM activity assays
  • Bromodomain and chromodomain binding studies
  • Epigenetic inhibitor screening
  • Chromatin-mark specificity profiling

Mechanism of action

[Lys(Ac)27]-Histone 3 (21-44)-GK(Biotin); H3K27(Ac), biotin-labeled sits within the Histone / Epigenetic research class (CPC reference HIST-051). These peptides carry defined post-translational modifications (methylation, acetylation, phosphorylation) at N-terminal histone tail residues, allowing biochemical characterization of writers (HMTs, HATs), erasers (KDMs, HDACs), and readers (bromodomains, chromodomains). Investigators typically incorporate [Lys(Ac)27]-Histone 3 (21-44)-GK(Biotin); H3K27(Ac), biotin-labeled as a reference standard, tool ligand, or substrate in the assay contexts listed above. SPR / BLI binding, AlphaScreen, TR-FRET, and MS-based activity assays.
