ChIPresultsobtainedwiththeantibodydirectedagainstMeCP2
ChIPassayswereperformedusinghumanosteosarcoma(U2OS)cells,theantibodyagainstMeCP2(Cat.#25304)andoptimizedPCRprimersets.Shearedchromatinfrom1x106cellsand5µgofantibodywereusedperChIPexperiment.IgG(1µg/IP)wasusedasanegativeIPcontrol.QuantitativePCRwasperformedwithprimersforthepromotersoftheZMYND10gene(usedasapositivecontrol)andCDC6gene(usedasanegativecontrol).Figure1showstherecovery,expressedasa%ofinput(therelativeamountofimmunoprecipitatedDNAcomparedtoinputDNAafterqPCRanalysis).
Determinationoftheantibodytiter
Todeterminethetiteroftheantibody,anELISAwasperformedusingaserialdilutionoftheantibodydirectedagainstMeCP2(Cat.#25304)andthecrudeserum.Theplateswerecoatedwiththepeptideusedforimmunizationoftherabbit.Byplottingtheabsorbanceagainsttheantibodydilution(Figure2),thetiterofthepurifiedantibodywasestimatedtobe:1:32,900.
