Primer3

The standard tool for PCR primer design

Primer3 is the workhorse behind most PCR primer design. It optimizes primers against melting temperature, GC content, secondary structure and specificity constraints.

Highlights

  • Fine control over Tm, length, GC and self-complementarity.
  • primer3-py provides a Python binding for pipelines.
  • Powers many web primer-design tools.
