Oligonucleotide Properties Calculator

Written by Super User. Posted in Calculators

Calculator for oligonucleotide properties.

Calculate the properties of a oligonucleotide.

Calculate the Length, Molecular Weight, Melting Temperture (Tm), GC content and more of an oligonucleotide

Enter Oligonucleotide Sequence Below
OD calculations are for single-stranded DNA or RNA
Nucleotide base codes
