The first CO 2 exposure experiments on several species of pelagic copepods inhabiting surface and deep layers in the western North Pacific were conducted. Living organisms were collected from two layers between the surface and 1,500 m between latitudes of 11 and 44°N, and they were exposed aboard ship to various pCO 2 up to about 98,000 µ µ µ µ µatm.(More)
We examined the genomic structure of the reeler gene in Orleans reeler mouse mutant. Exon skipping of the reeler gene caused a 220 bp deletion in the transcript, resulting in a frame shift of the reeler gene which disrupts the 8th EGF-like motif of the reeler product. Surprisingly, the skipped exon was inserted by the 7104 bp L1 element which carried the(More)
We report here an improved protocol for the preparation of full-length cDNA libraries that improves the previously reported method (Carninci, P., Kvam, K., Kitamura, A. et al. 1996, Genomics, 137, 327-336), that allows long cDNAs to be cloned more efficiently. One potential disadvantage of the original biotinylated CAP trapper protocol is the exposure of(More)
The specific objective of our project on CO 2 ocean sequestration is to investigate its technical feasibility and to improve the understanding of any associated environmental impacts. Our ultimate goal is to minimize any impacts associated with the eventual use of ocean carbon sequestration to reduce greenhouse gas concentrations in the atmosphere. The(More)
We developed a new simple high-throughput plasmid DNA extraction procedure, based on a modified alkaline lysis method, using only one 96-well microtiter glassfilter plate. In this method, cell harvesting, lysis by alkaline and plasmid purification are performed on only one microtiter glassfilter plate. After washing out RNAs or other contaminants, plasmid(More)
