We recommend that for standard (20 µL) TaqMan Array Plates, you use either the Universal Master Mix (I or II) or the Gene Expression MasterMix. For fast (10 µL) TaqMan Array Plates, use the Fast Universal Master Mix. The Fast Advanced Master Mix can also be used for either plate type, but we recommend following the protocol in this manual (https://assets.thermofisher.com/TFS-Assets/LSG/manuals/MAN0025706_TaqManFastAdvMM_UG.pdf).
