Description
Application
Activation Coupling Reagent for Nucleic Acid Synthesis.
Purpose
it is used as an activator in phosphoramidite-based DNA and RNA synthesis. It activates nucleoside phosphoramidites so they can efficiently couple with the growing oligonucleotide chain.
General Description
5-Ethylthiotetrazole (ETT) is an efficient activator for use in chemical synthesis of either DNA or RNA. ETT has excellent performance with respect to coupling times coupling efficiency consumption of phosphoramidites and reduction of n-1 impurities.
