Cell dissociation

Our cell dissociation reagents help you prepare a desired number of cells and plate them so that they are healthy, proliferating, and in a desired confluency at the time of transfection.

Successful transfection is influenced by many factors—the choice of the transfection method, health and viability of the cell line, number of passages, degree of confluency, quality and quantity of the nucleic acid used, and the presence or absence of serum in the medium can all play a part in the outcome of your transfection experiment. While it is possible to optimize specific transfection conditions to achieve high transfection efficiencies, it is important to note that some cell death is inevitable regardless of the transfection method used.
