Abstract: By using a wide-pore(30 nm),microspheric silica(8μm)as the matrix and γaminopropyltriethoxysilane as the coupling agent,a stationary phase of biospecific affinity chromatography was prepared by chemical binding nicotinamide adenine dinucleotide(NAD) to the γ-aminopropyl modified silica. Using the phosphate buffer(pH=7.0)as a mobile phase,the separation of some nucleotides is accomplished by the detection of UVD(260 nm).The effect of changed ion strengh of eluent on the resolution of nucleotide(AMP, ADP and ATP)has been studied.
