Handling, storage & reconstitution

General guidance for this class

Reference standards in the Histone / Epigenetic class are typically shipped as lyophilized powder and stored desiccated at −20 °C protected from light. Once reconstituted in bacteriostatic water or the assay-appropriate buffer, aliquot and store at −80 °C to minimize freeze–thaw cycles. Confirm handling requirements against your institutional biosafety and radiation protocols before use.

Mechanism & research applications

[Lys(Ac)27]-Histone H3 (21-43)-GGK(Biotin), H3K27(Ac), biotin-labeled sits within the Histone / Epigenetic research class (CPC reference HIST-052). 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 H3 (21-43)-GGK(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.

Studied for

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