50 µg recombinant HDAC8 supplied in a buffer of 40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 200 mM imidazole and 20% glycerol.


HDAC8 (Histone Deacetylase 8) is responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Also involved in the deacetylation of cohesin complex protein SMC3 regulating release of cohesin complexes from chromatin. May play a role in smooth muscle cell contractility.

Application Notes

Recombinant HDAC8 is suitable for use in histone deacetylase (HDAC) assays. It can also be used to study enzyme kinetics, inhibitor screening, and selectivity profiling.

Specific Activity: 300 pmol/min/μg.

Protein Details

Full length recombinant human HDAC8 was expressed in a baculovirus expression system (accession number NM_018486) with a C-terminal His-Tag. The molecular weight of the protein is ~46.4 kDa.

25mM Tris-HCl, pH 8.0, 137mM NaCl, 2.7mM KCl, 1mM MgCl2, 0.05% Tween 20 and 20 µM HDAC class 2a substrate. Incubate 30 min at 37ºC, followed by incubating with developer at RT for 20 minutes. Fluorescence intensity is measured at exc360/em460.


Recombinant proteins in solution are temperature sensitive and must be stored at -80°C to prevent degradation. Avoid repeated freeze/thaw cycles and keep on ice when not in storage.
