WebKCl buffer: Here, the potassium or K+ ion promotes primer annealing. (NH4)2SO4 buffer : It is an alternative to the KCl buffer. Here, the ammonium or NH4+ ion enhances specificity … WebAnother approach to promoting specificity is to modify the PCR cycling parameters. In touchdown PCR, the annealing temperature of the first few cycles is set to be a few degrees higher than the highest melting temperature (T m) of the primers [1,2].Higher temperatures help destabilize the formation of primer-dimers and nonspecific primer-template …
