产品描述

General description

Dimethyl sulfoxide is a free radical scavenger and a cryopreservant. It elicits protective effect in double stranded breaks(DSBs).[1] Dimethyl sulfoxide (1-10%) has been shown to accelerate strand renaturation and is believed to give the nucleic acid thermal stability against depurination.[2] As a PCR cosolvent, DMSO may help improve yields, especially in long PCR.[3]

Application

Dimethyl sulfoxide has been used as a component of polymerase chain reaction (PCR) mixture[4] and as PCR facilitator.[2][5]

Caution

容易过度冷却,并在室温下缓慢融化固化的产品放在室温下可以再次液化,对其本身无影响。
