SpletSSP stringency is multifactorial, relying on the concentration of all the PCR constituents such as target DNA, Taq, dNTPs, Tris, and free magnesium. PCR stringency kinetics also relies on individual primer factors, such as primer sequence, length, and type of primer-template mismatches. SpletThe discussed aspects include the size and molecule type of the selected target, the nature and stringency of the selection process, the amplification step with its possible PCR bias, the efficient regeneration of RNA or single-stranded DNA, and the different sequencing procedures and screening assays currently available.
