About PCR Primer Reverse Complement Tool
Generate the reverse complement (5′→3′) of a PCR Primer sequence — for designing the reverse primer. Runs in your browser; the sequence is never uploaded. The stakes: Primer design, GC content and melting temperature decide whether a PCR amplifies cleanly or produces nothing. Small sequence mistakes propagate into failed experiments and wasted reagents. Reverse-complementing is the basis of designing the reverse primer. Watch out for: ignoring secondary structure in GC-rich templates; reading the wrong strand or frame; mismatched forward/reverse primer Tm. Because the calculation happens entirely client-side, you can use it offline and with confidential data, then cite the stable URL in your methods or teaching notes.

Frequently asked questions
Any tips specific to this calculation?+
Reverse-complementing is the basis of designing the reverse primer. Also watch out for: ignoring secondary structure in GC-rich templates and primers with runs of G/C causing mispriming.
Is this pcr primer reverse complement tool free to use?+
Yes. It is completely free, needs no sign-up, and runs entirely in your browser — there are no usage limits.
What formula does it use?+
The exact formula and a step-by-step worked example are shown beneath the result.
What are the most common mistakes here?+
In nucleic-acid sequence analysis, watch for: mismatched forward/reverse primer Tm; primers with runs of G/C causing mispriming; ignoring secondary structure in GC-rich templates; reading the wrong strand or frame. This tool shows the working so you can catch these before they cost an experiment.
Does my data leave my device?+
No. All computation happens locally in your browser. Nothing you enter — sequences, concentrations or measurements — is uploaded to any server, so it is safe for confidential work.
Can I cite this tool?+
Yes — use the “Cite this tool” snippet on the page. Many users link these calculators from methods sections, lab SOPs and teaching materials.
