An n-hexane/water solution was used to dissolve samples, and then extracted-ion-chromatogram mode was used to quantify methyl methanesulfonate and ethyl methanesulfonate. Calibration curves showed good linearity over the studied range for methyl methanesulfonate and ethyl methanesulfonate. WebEthyl methane sulfonate (EMS) mutagenesis in Arabidopsis is the most widely used mutagenesis technique. EMS has high mutagenicity and low mortality and can be used in any laboratory with a fume hood. The chemical principle of EMS mutagenesis is simple; it is based on the ability of EMS to alkylate guanine bases, which results in base mispairing. leadedge logistics pvt ltd
