An efficient chimera formation method by tissue culture combined with grafting was studied in Brassica. Cabbage cultivars “Ruby-ball” and “YR-ranpou” (Brassica oleracea) were used for intervarietal chimera formation. Seven-day-old seedlings leaving one of two cotyledons were approach-grafted and cultured in vitro (AGSC method). Chimeric shoots were obtained(More)
The characteristics of intervarietal and interspecific chimeras synthesized by the graft-culture method were determined by morphology, anthocyanin pigmentation pattern, and crossing. In an intervarietal chimera between ‘YR-ranpou’ (green cabbage) and ‘Ruby ball’ (red cabbage) in Brassica oleracea, a segregation phenomenon was noted in which seeds giving(More)
Carbon nanotubes (CNTs) are important materials in advanced industries. It is a concern that pulmonary exposure to CNTs may induce carcinogenic responses. It has been recently reported that CNTs scavenge ROS though non-carbon fibers generate ROS. A comprehensive evaluation of ROS scavenging using various kinds of CNTs has not been demonstrated well. The(More)
On-line capillary isoelectric focusing-mass spectrometry (cIEF-MS) was applied to determine concentrations of peptides and proteins using angiotensin II and human tetrasialo-transferrin as the model samples. The concentration of the carrier ampholyte was optimized for both resolution and ion intensity. cIEF-MS employing 1% Pharmalyte 3-10 and a sheath(More)
