実験手順: Targets are complementary oligonulceotides labeled with fluorescent dye Cy3. Slides were hybridized with targets in hybridization buffer (2×SSC, 0.1% SDS and complementary target at 100 nM) at room temperature for 1 hr and washed in 2×SSC, 0.1% SDS for 5 min., 0.1×SSC, 0.1% SDS for 10 min., and finally in 0.1×SSC for 1 min. All washings were carried out at room temperature. Results show that the aldehyde slides prepared from photoactivatable silane gave much higher hybridization signal than non-aldehyde slides. washed in 2×SSC, 0.1% SDS for 5 min. finally in 0.1×SSC for 1 min were carried out at room temperature Results

実験手順: A 300-mL stainless steel autoclave equipped with a magnetically driven stirrer was charged under nitrogen with rhodium (14.55 mg of rhodium, 0.14 mmole charged as the 2-ethylhexanoate salt), α,α'-bis(diphenylphosphino)-o-xylene ligand (0.16 gm, 0.34 mmole), 1-octene (22.44 grams), and toluene (70 mL). This was pressured to 300 psig with a 1/1 mixture of hydrogen/carbon monoxide (synthesis gas) and heated to 105° C. The autoclave was repressured to 300 psig with the synthesis gas mixture whenever the pressure dropped to 250 Psig. The reaction was kept at 105° C. for 2 hours, during which time a total pressure drop of 460 psig was observed. The mixture was analyzed by gas/liquid chromatography and showed a 94.3 percent conversion of 1-octene. A 90.6 percent yield to isomeric nonanal products was obtained based on 1-octene charged. The ratio of linear/branched nonanal product was 3.47/1. The autoclave was repressured to 300 psig with the synthesis gas mixture whenever the pressure dropped to 250 Psig

実験手順: 1-Decene was supplied from a raw-material tank 4 using a high-pressure pump, and the raw material was preheated in an ozonization reaction vessel 3 at 20° C. The preheated raw material was then combined with the high-pressure carbon dioxide solution of ozone, and continuous ozonization proceeded in a stainless steel coil-shaped ozonization reaction section 1 having an inside diameter of 1 mm and a length of 26 cm and set to 20° C. The reaction mixture that exited from the ozonization vessel 3 was subsequently subjected to a continuous thermal decomposition reaction in a stainless steel coil-shaped decomposition reaction section 11 having an inside diameter of 1 mm and a length of 100 cm and set to 200° C. The residence time corresponding to the reaction time was 6 seconds in the ozonization reaction section and 24 seconds in the decomposition reaction section, making a total of 30 seconds. The product was passed via the pressure-regulating valve 30 and was dissolved in acetone placed in a gas-liquid separation device 40. Quantification of the acetone solution by FT-NMR using coumarin as an internal standard confirmed that 0.58 mmol of nonanoic acid and 0.63 mmol of nonanal were produced in 30 minutes. set to 20° C set to 200° C The residence time corresponding to the reaction time was 6 seconds in the ozonization reaction section and 24 seconds in the decomposition reaction section a total of 30 seconds placed in a gas-liquid separation device 40
