Preparation Note

Trichloroacetic acid / Dichloromethane 3/100 (v/v)

Other Notes

Deblock solution containing trichloroacetic acid (TCA) in dichloromethane 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. Removal of the DMT allows the unprotected 5′hydroxyl moiety to react with a new phosphoramidite in a subsequent extension reaction.
