应用
BES is used as a buffer to maintain the pH of the solutions in biological experiments. It is useful for diagnostic assay manufacturing industry. It induces cross-linking between sulfonated polyimide chains in sulfonated polyimide membranes. It acts as biobuffer to investigate the aqueous medium self-assembly of heterometallic CuII/Li 3D coordination polymers. 备注

产品说明 一般描述 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.

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. 包装 25 g in Plastic ampoule
