1 Location: Ideally, the probe should be in close proximity to the forward or reverse primer, but should not overlap with a primer-binding site on the same strand. 2  Probes can be designed to bind to either strand of the target. 3  Melting temperature (Tm): Preferably, probes should have a Tm 6â8Â°C higher than the primers.
What is Mercury Retrograde? Mercury Retrograde happens three to four times per year, when the planet Mercury slows down, and appears to stop (station) and move backward (retrograde). It's an optical illusion, since there is forward movement, like speeding by a slow-moving trainâas it recedes, it appears to go backward.
