About

bioinformatics.tools is a free set of calculators for the everyday arithmetic of molecular biology: reverse complements, melting temperatures, ligation ratios, dilutions, alignments, dose-response fits.

How it works

Each tool is one page of JavaScript that runs in the browser. Sequences and measurements stay in the tab and are never sent to a server. There is no account, no quota and no job queue, and a page keeps working offline once it has loaded.

What to expect

Accuracy

The tools are meant for planning and quick checks. Verify a result independently before it decides an experiment, and never use one for clinical decisions. See the terms.
