Q: Does dsDNase cleave ssDNA?
A: No, dsDNase cleaves only double-stranded DNA. However, if ssDNA forms double-stranded structures, it will act as a target for dsDNase. Because of this, long and complex ssDNA may be partially degraded. Therefore we recommend additional dsDNase inactivation step for RT-PCR amplification of targets 3 kb or longer. The inactivation step should be performed by 5 min incubation at 55 degrees C in the presence of 10 mM DTT. |
