Competent Cell Preparation

submitted by: abnova

Abnova - Competent cells are those that possess more easily altered cell walls that DNA can be passed through easily. Because DNA is hydrophilic, it will not normally pass through membrane. In order to make these cells readily incorporate foreign DNA, they must first be made "competent" to take up foreign DNA. More videos, visit Abnova!

Calcium Phosphate Transfection

submitted by: abnova
Abnova - Calcium phosphate transfection method is a simple, time efficient and relatively inexpensive way to introduce DNA into cells in stable cell lines such as HEK293T, CHO and BHK cells. This method works best in cell lines that are highly transformed and adherent and this technique requires few manipulative steps and maintains high levels of reproducibility from experiment to experiment.
