Primer3 is a widely used program for designing PCR primers (PCR = "Polymerase Chain Reaction"). PCR is an essential and ubiquitous tool in genetics and molecular biology. Primer3 can also design hybridization probes and sequencing primers. PCR is used for many different goals.
Primer3 picks primers for PCR reactions, considering as criteria: o oligonucleotide melting temperature, size, GC content, and primer-dimer possibilities, o PCR product size, o positional constraints within the source (template) sequence, and o possibilities for ectopic priming (amplifying the wrong sequence) o many other constraints.
There are several available versions of the Primer3 web interface: Primer3Web and Primer3Plus. Primer3Web. Primer3Web is the original web-interface to Primer3. Primer3Web was developed by Steve Rozen and Helen Skaletsky. Primer3Web is maintained by Triinu Koressaar and Maido Remm. Primer3Web at primer3.ut.ee. Primer3Plus
