Competent cells for everyday bacterial transformation have broad utility for propagating vectors, subcloning DNA fragments, and other routine molecular biology procedures. To accommodate various workflows, the most popular competent cells for subcloning come in several formats including standard, One Shot, and MultiShot packaging.
