1 General guidelines for primer design 18-30 nucleotides G/C content: 40-60% Avoid complementary sequences of primers (especially at the 3’ end) Avoid mismatches at the 3’ end Avoid 3 or more G or C at the 3’ end Avoid a 3’ end T

2 Primer design to eliminate amplification from contaminating genomic DNA

3 Primer design to detect amplification from contaminating genomic DNA
