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.
As you face the front of a vessel, port is left, starboard is right, forward is forward (obviously) and aft is toward the stern. The bow is the front of the vessel, the stern is the back. These are not directions, but are parts of the vessel. Except, astern is a direction meaning toward the back or reverse.
