We suggest using Universal Master Mix (I or II) or Gene Expression MasterMix for standard (20 µL) TaqMan Array Plates. For fast (10 µL) plates, opt for Fast Universal Master Mix. While Fast Advanced Master Mix can be used for both, we advise following the manual's protocol (https://assets.thermofisher.com/TFS-Assets/LSG/manuals/MAN0025706_TaqManFastAdvMM_UG.pdf).
