My probe has an extra peak on the MALDI-TOF trace at -300.

When the laser used in MALDI-TOF hits the dye 20-30 times, it tends to "knock off" part of the quencher and there is always a -300 dalton peak on the trace. This does not occur in a standard RT machine and should not affect your experimental results.
