IDT SciTools® Web Tools

These software applications determine the properties of any oligo sequence entered, as well as facilitate the intelligent design of assay conditions, all at the click of a button. The suite is easy to use and makes it simple to add each optimized oligonucleotide to an ongoing order list ready for purchase.


Analyze primers, probes, RNAi oligos and more. Identifies melting temperature, hairpins, dimers and mismatches.

Use OligoAnalyzer v 3.1 »


Create highly customized designs for PCR primers and qPCR assays.
