mass spectrometry; polyacrylamide gel electrophoresis; proteins; proteomics
Abstract:
... A sensitive and convenient “visible SYPRO” staining protocol was developed for visualizing proteins after SDS-PAGE. Gels were sensitized with SYPRO Ruby and then stained with the Coomassie Brilliant Blue G-250 protocol (Blue Silver). This combined protocol had similar or better linearity than staining with only SYPRO Ruby or Blue Silver, respectively. In addition, this method was more sensitive th ...

Abstract:
... Fissidens macaoensis L. Zhang is described as a new species from Macao, South China. The species can be separated from its congeners by a suite of characters, including (1) minute size; (2) subterraneous tubers, composed of one to several cells, growing laterally from mature rhizoids; (3) abundant rhizoidal gemmae found on the surface of the soil and which are developed from subterraneous rhizoids ...

Abstract:
... The rice (Oryza sativa L.) elongated uppermost internode (eui) gene effectively results in a recessive tall plant type. In eui background, we found a mutant 02428ha that exhibited a semidwarf phenotype. Because semidwarf varieties possess high yield potential, this mutant may be useful for hybrid rice breeding. The present study aimed to characterize the dwarfing mechanism in the mutant. Microscop ...

The yeast proteins, Msb3p and Msb4p, are two Ypt/Rab-specific GTPase-activating proteins sharing redundant functions in exocytosis, organization of the actin cytoskeleton, and budding site selection. To see if Msb3p might play an additional, specific role, we first tested the sensitivities of msb3 and msb4 mutant strains to different drugs and then screened a genomic library for multicopy suppress ...
