Competent cells are those that have had their cell walls altered to render it easier to incorporate foreign DNA into their interiors. Cells are made competent by a process that uses calcium chloride and heat shock, and cells that are undergoing very rapid growth are made competent more easily than cells in other stages of growth. Factors such as transformation efficiency, genetic markers, and packaging formats will impact the time and effort required for your project, and so too its success. Choose from a number of cell types and formats to ensure optimal function.

BLR Competent Cells, Expression Strains, MilliporeSigma

Supplier: MilliporeSigma

A common method for transformation of plasmids into E. coli is the use of chemically competent cells. Although competent cells can be prepared in the laboratory, greater efficiency, reproducibility, and convenience are achieved using Novagen® prepared competent cells. Every Novagen® competent cell strain is verified for phenotype and purity, and is guaranteed for transformation efficiency.
