Assays & Kits

The HDAC11 Fluorogenic Assay Kit is a complete assay system designed to measure histone deacetylase 11 (HDAC11) activity for screening and profiling applications. The HDAC11 Fluorogenic Assay Kit is based on a unique fluorogenic substrate and developer combination. This assay method eliminates dealing with the radioactivity, extraction, and chromatography aspects of traditional assays. Using this kit, only two simple steps on a microtiter plate are needed to analyze the HDAC11 activity level. First, the HDAC fluorometric substrate, containing an acetylated lysine side chain, is incubated with purified HDAC11. The deacetylation sensitizes the substrate so subsequent treatment with the Lysine Developer produces a fluorophore that can then be measured using a fluorescence reader. HDACs regulate cellular processes by catalyzing the hydrolysis of an acetyl group from acetyllysines in modified proteins. In the HDAC assay, fluorescent-dye molecules are attached to a peptide containing acetyl

A fluorogenic, myristoylated lysine peptide substrate for Sirtuin 6. This substrate should be used in conjunction with SIRT Developer, #50089. Optimal excitation wavelength 350-380 nm, emission wavelength 440-460 nm.

The SMYD2 Chemiluminescent Assay Kit is designed to measure SMYD2 activity for screening and profiling applications. The key to the SMYD2 Chemiluminescent Assay Kit is a highly specific antibody that recognizes a methylated residue of Histone H3. With this kit, only three simple steps are required for methyltransferase detection. First, S-adenosylmethionine is incubated with a sample containing assay buffer and the SMYD2 methyltransferase enzyme. Next, primary antibody is added. Finally, the plate is treated with an HRP-labeled secondary antibody followed by addition of the HRP substrate to produce chemiluminescence that can then be measured using a chemiluminescence reader.

Biotinylated histone H4 peptide (a.a. 1-21) asymmetrically di-methylated at Arginine 3. It also contains a C-terminal GG linker, followed by a biotinylated Lys.

This peptide is histone H4 (1-23) monomethylated at Arg3 followed by a biotinylated Lys conjugated to a C-terminal GG linker. Methylation of Arg3 is catalyzed by PRMT1 and functions to promote p300 acetylation of histone H4.

A peptide substrate for Histone 3, K4,K9 methyltransferases. The peptide corresponds to residues 1-21 of histone H3.

Histone H3 Peptide, a.a. 1-21, biotin conjugated. This sequence corresponds to the first 21 amino acids of the NH2 terminal of histone H3 followed by a GG linker and a biotinylated lysine.

S-adenosyl homocysteine conjugated to fluorescein.

A peptide substrate for Histone 4 R3 methyltransferases. The peptide corresponds to amino acid residues 1-21 of histone H4.
