FIELD: biotechnology, biochemistry.
SUBSTANCE: method for preparing DNA preparation involves separation of components from preliminary disrupted bacterial cells by electrophoresis in U-shaped tube and selection of DNA-containing fraction on interface of buffer and sample. Applying the invention allows simplifying the process for preparing the preparation of bacterial DNA for carrying out polymerase chain reaction. Invention can be used in laboratory and scientific practice for preparing the preparation of bacterial DNA.
EFFECT: improved preparing method.
