Popis: A new kind of silane coupling agent, N-(beta-aminoethyl)-gamma-aminopropyl triethoxysilane, was used for DNA direct attachment on the surfaces of glass supports, then the immobilized DNA was hybridized with horseradish peroxidase (HRP)-labeled probe, and detected by using enhanced chemiluminescent method. In comparison with gamma-aminopropyl triethoxysilane, the detection limits (S/N) of DNA were 10 pg and 75 pg respectively. Several experimental conditions of DNA attach-ING to glass supports were investigated, and the system of hybridization of nucleic acid on the surfaces of glass supports was developed.
