Itbelongstothetransforminggrowthfactor-βsuperfamily.
AMHcausesapoptosisofspecificAnti-Müllerianinhibitingsubstance(MIS)receptor-bearingcells,whilehavingnoeffectoncellswithoutreceptors.
AMHisalsoexpressedingranulosacellsofpreantralandsmallantralfolliclesintheovary,andAMHinhibitsrecruitmentofprimordialfolliclesintothepoolofgrowingfollicles,anddecreasesresponsivenessofgrowingfolliclestoFSH.
PRINCIPLEOFTHETESTTheRatandMouseAMHELISAisaquantitativethree-stepsandwichtypeimmunoassay.
InthefirststepseriallydilutedCalibratorsandunknownsamplesareaddedtoAMHantibodycoatedmicrotiterwellsandincubated.
Afterthefirstincubationandwashing,thewellsareincubatedwithbiotinylatedAMHantibodysolution.
Aftersecondincubationandwashing,thewellsareincubatedwithstreptavidinhorseradishperoxidaseconjugate(SHRP)solution.
Afterthethirdincubationandwashingstep,thewellsareincubatedwithsubstratesolution(TMB)followedbyanacidicstoppingsolution.
Inprinciple,theantibody-biotinconjugatebindstothesolidphaseantibody-antigencomplexwhichinturnbindstothestreptavidin-enzymeconjugate.
Theantibody-antigen-biotinconjugate-SHRPcomplexboundtothewellisdetectedbyenzyme-substratereaction.
Thedegreeofenzymaticturnoverofthesubstrateisdeterminedbydualwavelengthabsorbancemeasurementat450nmasprimarytestfilterand630nmasreferencefilter.
TheabsorbancemeasuredisdirectlyproportionaltotheconcentrationofAMHinthesamplesandcalibrators.
