DCA DEBLOCK 2.5L 4 PACK (C005B-227221)

General description

Deblock solution contains dichloroacetic acid (DCA) in dichloromethane that assists in the removal of the dimethoxytrityl (DMT) protecting group from the 5′hydroxyl moiety of nucleotides already incorporated into the growing nucleic acid, before the addition of the next phosphoramidite. Removal of the DMT allows the unprotected 5′hydroxyl moiety to react with a new phosphoramidite in a subsequent extension reaction.

Preparation Note

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