基本信息
| NACRES | NA.21 |
| Preparation Note【制备说明】 | 三氯乙酸/二氯甲烷 3/100 (v/v) |
| Other Notes【其他说明】 | 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. |
