Plasmid transformation is a foundational technique in life science research in fields such as molecular biology and protein science. Transformation is a process of horizontal gene transfer of exogenous DNA into a host cell (typically bacterium) where it can be cloned by the host cell in large numbers. While this technique can occur naturally, not all bacteria are capable of taking up exogenous DNA or do it at a sufficient rate to be tractable in the laboratory. Using chemicals or electrical pulses, however, one can generate artificially competent bacterial cells capable of uptaking exogenous DNA at high levels.
In this booklet, we provide a series of studies, protocols and reviews focusing on the theory, technique and applications of plasmid transformation. Through the presented article summaries and application note, we hope to educate researchers on important considerations and strategies to enhance the efficiency for successful plasmid DNA transformation.
