Thermally resistant nuclease in Serratia marcescens hinders PCR reactions and degrades PCR products

Polymerase chain reaction (PCR) is an important tool for exogenous gene acquisition and recombinants identification. There exist two problems when using Serratia marcescens as a template for PCR amplification: amplified PCR products are rapidly degraded, and the results of PCR amplification are unst...
