Primer >16 nucleotides in length are not generally annealed specifically to non-target DNA sequence (e.g. human DNA in an assay for bacterial infection). For example, a short primer sequence, such as a 12 bp oligonucleotide, binds to 200 specific annealing sites in the human genome. (The ...

8. Runs: Primers with long runs of a single base should generally be avoided as they can misprime. For example, AGCGGGGGATGGGG has runs of base 'G' of value 5 and 4. A maximum number of runs accepted is 4bp.9. 3' End Stability: It is the maximum ΔG value of the five ...
Time should also be spent determining the optimal primer concentration and it is best to try a range of final concentrations from 0.1 µM to 0.5 µM for both primers. For some assays the optimal concentration for the two primers will not be the same, for example, to achieve good melt...

(B) With indirect PCR cloning, amplicons are modified, for example by restriction digestion, prior to insertion into compatible vectors. Since primers are synthesized in a 3′ to 5′ direction, failed or incomplete synthesis of these DNA olig...
Try to avoid runs of 4 or more of one base, or dinucleotide repeats (for example, ACCCC or ATATATAT). Avoid intra-primer homology (more than 3 bases that complement within the primer) or inter-primer homology (forward and reverse primers having complementary sequences). These circumstances ...
