Growth and selection of clones from "summary" of Molecular Cloning by Joseph Sambrook,David William Russell
The growth and selection of clones are critical steps in molecular cloning experiments. After transformation of a vector containing the gene of interest into a host cell, it is necessary to identify and isolate the cells that have successfully taken up the vector. This process involves growing the transformed cells on selective media that contain antibiotics or other agents that kill cells lacking the vector. By exposing the transformed cells to selective conditions, only those that have incorporated the vector will survive and proliferate. These surviving cells will form colonies on the agar plates, each representing a clone derived from a single transformed cell. The growth of these clones allows for the amplification of the gene of interest within the host cells. To further characterize the clones, it is necessary to screen them for the presence of the desired gene or DNA fragment. This can be accomplished through a variety of methods, such as colony PCR, restriction enzyme digestion, or sequencing. By confirming the presence of the gene of interest in the clones, researchers can proceed with additional experiments or analyses. The process of growth and selection of clones is essential for the successful completion of molecular cloning experiments. It allows researchers to isolate and amplify the gene of interest, paving the way for further studies on its function and regulation. By carefully monitoring the growth and selection of clones, researchers can ensure the accuracy and reproducibility of their results.
