BackgroundInformation
Acetylationofhistones,includinghistoneH3,hasbeeninvolvedintheregulationofchromatinstructureandrecruitmentoftranscriptionfactorstothegenepromoters.Histoneacetyltransferases(HATs)andhistonedeacetylases(HDACs)playacriticalroleincontrolofhistoneH3acetylationatmultiplesites.HistoneH3atlysine18(H3-K18),alongwithK9andK14,areprimaryacetylatedsitesofhistoneH3.AcetylationofhistoneH3-K18istightlyinvolvedinthecellcyclereguation,cellproliferationandapoptosis.AcetylationofhistoneH3-K18isalsocorrelatedwithtranscriptionactivation.AnimbalanceintheequilibriumofhistoneH3acetylation,includingK18acetylation,hasbeenassociatedwithtumOrigenesisandcancerprogression.HistoneH3-K18acetylationmaybeincreasedbyinhibitionofHDACsanddecreasedbyHATinhibition.Thus,quantitativedetectionofglobalacetylhistoneH3-K18wouldprovideusefulinformationforbetterunderstandingepigeneticregulationofgeneactivation,andfordevelopingHATorHDAC-targeteddrugs.TheEpiQuik™GlobalAcetylHistoneH3-K18QuantificationKit(Colorimetric)providesatoolformeasuringglobalacetylationofhistoneH3-K18.

Principle&Procedure
Thiskit isdesignedformeasuringglobalhistoneH3-K18acetylation.Inanassaywiththiskit,theacetylhistoneH3atlysine18iscapturedtothestripwellscoatedwithananti-acetylH3-K18antibody.ThecapturedacetylhistoneH3-K18canthenbedetectedwithalabeleddetectionantibody,followedbyacolordevelopmentreagent.TheratioofacetylH3-K18isproportionaltotheintensityofabsorbance.TheabsoluteamountofacetylH3-K18canbequantifiedbycomparingtothestandardcontrol.
