Objective To explore a genome DNA detection method with less time-consuming and high detection rate. Methods Genomic DNA samples were extracted and detected with improved ethidium bromide staining method. The sensitivity was verified with spectrophotometer meter.Polymerase chain reaction was used to confirm whether the method was available for detecting the PCR product. Results The improved ethidium bromide staining method significantly reduced the quantity of genomic DNA sample applied to gel,improved the ...
