What is Plasmid preparation?

Plasmid preparation, often called miniprep, midiprep, or maxiprep, refers to the process of isolating plasmid DNA from bacteria. It is a common technique in molecular biology and biotechnology used to obtain purified plasmid DNA for downstream applications such as cloning, sequencing, transfection, and gene therapy. The process typically involves bacterial culture, cell lysis, DNA purification, and elution of the plasmid DNA.
