Abstract:

The commercialisation of miniprep kits supplanted the original alkaline lysis method for plasmid DNA preparation, and had remained relatively unchanged for almost two decades. The Miraprep substantially improved the yields of miniprep kits. However, the method still relies on commercial kits, which can be a burden financially to certain projects. Additionally, Pronobis et al. also identified loss of RNAse activities in miniprep kits over time. The present novel plasmid DNA isolation protocol addresses the two issues mentioned above utilising alkaline lysis and alkaline hydrolysis principles. With a largely identical workflow and operation time, the Macerprep will significantly reduce costs of establishing new laboratories as well as maintenance of running molecular biology laboratories.
