摘  要:
[Objective] To establish a fast method to extract maize genome DNA. [Method] Improved CTAB method was further simplified, a method for rapid extraction of the maize genome DNA was established without the steps of alcohol precipitation,washing,dissolving and RNA digestion. [Result] The DNA integrity and the PCR amplification using this method showed no significant difference from the plant genomic DNA extraction kit method. Furthermore,it was same detection results with ELISA analysis and with PCR detection using DNA template obtained by this method. [Conclusion]Therefore,this method is a rapid,efficient,accurate,high-throughput method that meets the PCR detection requirements of genetically modified maize.
