Primary inducible fluorescence in secretory granules of tumor cells supravitally stained by a toluidine blue dye.
In a toluidine blue dye (British Drug Houses, batch no. 651880), we report a purple chromato graphic fraction (Rf—0,55) with a spectral absorption peak at 622 m/u, which has the property to induce immediate bright yellow fluorescence (primary inducible fluorescence) in cytoplasmic gra nules of tumor cells. The cells are unfixed, supravital stained and examined by fluorescence micro scopy. Th...
متن کاملEffect of the Ruby Laser Microbeam on Mitochondria of Kb Cells Supravitally Stained by Pinacyanol
With pinacyanol as the supravital stain, a preferential effect on mitochondria of KB cells was achieved by the irradiation with the ruby laser beam. The observation confirmed the results of other workers using janus green B in the same experimental system. The preferential effect on mitochondria was noted in the area extending 8-10 micro beyond the nonpreferential damage of 4-5 micro in diamete...
متن کاملLack of toxicity of methylene blue chloride to supravitally stained human mammary tissues.
Methylene blue chloride (MBC) has been used previously as a supravital stain to facilitate the excision and subsequent transplantation of mammary epithelial structures by delineating them from surrounding connective tissue and fat, which stain less intensely. This study was undertaken to determine why MBC selectively stains epithelium and if it has any long-term toxicity to epithelial cells. Li...

متن کاملMicromanipulative Studies on Gelatinized Starch Granules.
Gelatinized starch granules are generally considered to be comprised of sacs or outer membranes of starchy material enclosing a more or less fluid colloidal starch dispersion [see reviews by RADLEY (10)] and KERR (6). NXGEI, (9) and MEYER (8) considered the membrane to be precxistent in the native, ungelatinized granule. ALSBERG (1) and BADENHUIZEN (2, 3) on the other hand, concluded that the m...
