产品特性:

TFA-氨基己基亚磷酰胺可用于在寡核苷酸的5'端产生功能性胺基。 使用正常的氨脱保护和裂解条件在溶液中裂解对碱不稳定的TFA保护基。

合成条件:稀释之前,请确保所有产品均在小瓶底部。稀释至建议的浓度,并在密封的小瓶中充分混合,以确保所有内容物均已溶解。

稀释度:100 µmol/mL

脱保护条件:该亚磷酰胺的脱保护条件将取决于用于合成寡聚物的亚磷酰胺的类型。如果使用快速脱保护亚磷酰胺,则在60℃的浓NH4OH中脱保护1小时。如果使用标准亚磷酰胺,则在60℃下于浓NH4OH中脱保护5小时。在氨气脱保护过程中将除去TFA基团。

在氨脱保护过程中,碱不稳定的保护基脱落。可以将粗官能化的5'胺低聚物与标记化合物反应,然后使用RP柱纯化进行纯化。

储存条件:-20°C,干燥。
