What are the key features of a TaqMan MGB probe?

TaqMan MGB probes have a nonfluorescent quencher at the 3´ end and a minor groove binder at the 3´ end that increases the melting temperature (Tm) of probe, allowing the use of shorter probes. For more information on MGB probes, please consult the following manual: "Primer Express v1.5 and TaqMan MGB Probes for Allelic Discrimination: All PCR Instruments: User Bulletin."

When using the TaqMan Gene Signature Plates, should I mix the reactions after adding the master mix and template to the wells containing lyophilized primers and probe?

No, but it is recommended that the plate be centrifuged to draw down the liquid to the bottom of the wells.

What are your recommendations for the best way to dilute and store my TaqMan probe?

The probe should be diluted in TE buffer [10 mM Tris-HCl, pH 8.0 (at 25°C), 1 mM EDTA]. We recommend storing your probes, both stocks and working solutions, at -20°C in aliquots. This is to cut down on the number of times the probe is subject to freeze-thaws. For detailed information on diluting primers and probes, please refer to the tutorial entitled "Reconstituting and Diluting Primers and TaqMan Probes".
