"I wish I had analyzed my primers before ordering for the third time. Now I check all my primers with NetPrimer before ordering" -Stacey McCann, Cancer Biology Program, Stanford University

About NetPrimer

NetPrimer combines the latest primer analysis algorithms with a web-based interface allowing the user to analyze primers over the Internet. All primers are analyzed for primer melting temperature using the nearest neighbor thermodynamic theory to ensure accurate Tm prediction. Primers are analyzed for all primer secondary structures including hairpins, self-dimers, and cross-dimers in primer pairs. This ensures the availability of the primer for the reaction as well as minimizing the formation of primer dimer. The program eases quantitation of primers by calculating primer molecular weight and optical activity. To facilitate the selection of an optimal primer, each primer is given a rating based on the stability of its secondary structures. A comprehensive analysis report can be printed for individual primers or primer pairs.
