说明

準備報告

Acetonitrile / 5-(Ethylthio)-1H-Tetrazole 100 / 3 (v/w)

其他說明

Activator solution, containing 5-(Ethylthio)-1H- tetrazole (ETT) in acetonitrile, are mixed with solutions of phosphoramidites during the extension step.
The activator reacts with the amidite group to form a highly reactive intermediate. The intermediate then forms an internucleotide bond with the detritylated 5′hydroxyl group of the growing oligonucleotide chain.
