    描述
    概述 BES buffer is suitable for use in systems where a calcium phosphate-DNA complex formation is desirable. 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.
    Absorbance (100 mM, 260 nm):≤0.05.
