OligoAnalyzer™ Tool

Understand the expected properties of your oligos before you order them.

  • Calculator for GC content, melting temperature (Tm), molecular weight, extinction coefficient, µg/OD, nmol/OD, and more
  • Identify secondary structure potential
  • Minimize dimerization
  • Use NCBI BLAST™
