A Simple Preparation of Mycoplasmal DNA Template for PCR from Biological Samples Using Effective Surfactants

[摘要] References(6)Cited-By(5)To prepare mycoplasmal DNA template for PCR from biological samples rapidly and easily, surfactants which can solubilize cell membrane effectively were investigated. 3-[(3-Cholamidopropyl) dimethylammonio]-1-propanesulfonate (CHAPS) was considered an effective surfactant. This surfactant could solubilize mycoplasma cell membrane without suppressing the polymerase reaction. In addition, proteinase K treatment played an important role in preparing mycoplasmal DNA template from a simulated biological sample. It was therefore considered that a combination of proteinase K- and CHAPS- added lysis buffer would be more useful in preparing mycoplasmal DNA template. We could detect PCR products by using the lysis buffer with a simulated lung emulsion sample containing mycoplasma organisms at 104 CFU per gram.
