| Abstract: | Rapid non-specific degradation of Serratia marcescens DNA extracted with guanidium thiocyanate, occurred within 10 min of incubation with restriction endo-nuclease enzymes. The described modified method based on chemical and enzymatic deproteinization produced preparations of Ser. marcescens DNA of high yield and quality which did not autodegrade when incubated with restriction endonucleases. |
