Chen and Okayama described an improved transfection system for the stable transformation of cells with plasmid DNA using BES buffer. The gradual formation of the calcium phosphate-DNA complex and its slow precipitation onto cells appears to be the most critical factor contributing to the high efficiency of stable transformations.
