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.

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
Primer design to eliminate amplification from contaminating genomic DNA
Primer design to detect amplification from contaminating genomic DNA
Primer design and analysis tools • Vector NTI • Primer 3 • IDT SciTools PrimerQuest Oligo Analyzer
Real-time PCR • QPCR • Real-Time Vs Traditional PCR Post PCR processing Poor agrose gel resolution (semi-quantitative) Detect end point of the reaction
