Abstract: A thermal negative type lithographic printing original plate has a photosensitive layer featuring high sensitivity, excellent reproducibility in FM screening, and excellent print durability and chemical resistance at a minute image portion. A photosensitive composition for the photosensitive layer contains an alkali soluble resin having a monomer unit represented by the formula (I), a silane coupling agent represented by the formula (II), an infrared absorber, a radical polymerizable initiator, and a polymerizable compound having an ethylenic double bond and an amount of the silane coupling agent is from 15 to 40% of the photosensitive composition by mass.

Abstract: Reaction data are obtained from a reaction between a testing sample and a probe carrier on which a plurality of blocks containing a number of probes are arranged. Initially, a signal is detected from the probe carrier having reacted with the testing sample. Then, a data sequence is prepared based on the detected signal. Subsequently, the data sequence is subjected to frequency transformation to obtain frequency-transformed data. Then, filtering is performed on the frequency-transformed data to leave a frequency component corresponding to a repetition of the blocks. Finally, the filtered data is subjected to inverse frequency transformation to thereby acquire reaction data.

Abstract: A process for rapid and simple assay of nucleic acid on the basis of competitive hybridization using a DNA microarray that comprises a step of hybridizing a labeled nucleic acid other than the target nucleic acid with one of the immobilized probes on the substrate, where the labeled nucleic acid has a known sequence complementary to the probe and can bind thereto specifically.
