BES buffer is suitable for use in systems where a calcium phosphate-DNA complex formation is desirable (Absorbance: <0.05 at 260 nm, 100 mM). Chen and Okayama describe an improved transfection system for the stable transformation of cells with plasmid DNA using BES buffer. The slow formation appears to be the most critical factor contributing to the high efficiency of stable transformations. Has a pKa of 7.12 at 20°C.

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.
