Peptide Sequence Manipulations

Primer Analyzer Tool (check temperature & GC content)

  1. primers should be 17-28 bases in length;
  2. base composition should be 50-60% (G+C);
  3. primers should end (3') in a G or C, or CG or GC: this prevents "breathing" of ends and increases efficiency of priming;
  4. Tms between 55-80oC are preferred;
  5. 3'-ends of primers should not be complementary (ie. base pair), as otherwise primer dimers will be synthesised preferentially to any other product;
  6. primer self-complementarity (ability to form 2o structures such as hairpins) should be avoided;
  7. runs of three or more Cs or Gs at the 3'-ends of primers may promote mispriming at G or C-rich sequences (because of stability of annealing), and should be avoided.
