For other salt forms or a guaranteed higher purity please inquire. 3'-O-Ac-TTP is an analogue of TTP with blocked 3’-hydroxy function, which can be used as a transient, pH-sensitive chain terminator during DNA polymerization. The acetyl group of 3'-O-Ac-TTP is sensitive towards alkaline conditions and can be split off at pH >12.5 within 30 min. to allow further subsequent polymerization steps.
