Primer Analyzer Tool (check temperature & GC content)

 * http://www.idtdna.com/analyzer/Applications/OligoAnalyzer/Default.aspx


 * 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.
