说明

一般描述

Cap 1 solution consists of n-methylimidazole, lutidine, and acetonitrile (ACN).

应用

Cap 1 is suitable for use after the phosphoramidite reaction/coupling step.

生化/生理作用

Cap 1 solution aborts chains bearing unreacted 5′hydroxyl groups due to failure of reaction with activated phosphoramidite (typically, 1 to 2% of growing oligonucleotide chains in each synthesis cycle). These unreacted 5′hydroxyl groups are capped with an acetyl group and thus rendered unreactive for subsequent synthesis steps.

制备说明

Acetonitrile / Lutidine / N-Methylimidazole 8/1/1 (v/v/v)
