Description

General description

Deblock solution containing dichloroacetic acid (DCA) in toluene removes the dimethoxytrityl (DMT) protecting group from the 5′hydroxyl moiety of nucleotides already incorporated into the growing nucleic acid, prior to the addition of the next phosphoramidite. This solution contains toluene / Dichloroactic Acid (97/3 v/v).

Application

DCA Deblock solution facilitates removal of the DMT that allows the unprotected 5′hydroxyl moiety to react with a new phosphoramidite in a subsequent extension reaction.

Preparation Note

Toluene / Dichloroacetic acid 97/3 (v/v)
