Oligonucleotides

Additional Quality Controls

MALDI-TOF Mass Spectrometry

This method provides the most precise information about the length, deprotection-product and the presence of labels for modified oligonucleotides over a broad range of lengths (up to 60 bases).

 

Fluorescence analysis

This nondestructive physical technique provides qualitative information about your fluorescent oligonucleotides.

 

RP-UHPLC

This is a very efficient technique giving quantitative information about the purity level of oligonucleotides from 15 to 40 bases long.


IEX-UHPLC

This technique is particularly adapted to quantify the purity level of oligonucleotides from 15 to 40 bases long.
