Сульфородамин G химические свойства, назначение, производство
Химические свойства
Sulforhodamine G is an orange-red solid soluble in water. It is a fluorescent compound with an excitation peak at 531nm and an emission peak at 552nm.
Использование
Sulforhodamine G can be incorporated in composites as a dye for characterizing fluorescent correlation spectroscopy based images. It can also be used in the development of an acceptor molecule that facilitates the emission of white light in a light emitting hybrid.
Подготовка
4-Formylbenzene-1,3-disulfonic acid and 3-(Ethylamino)-4-methylphenol?condensation, the products with sulfuric acid dehydration, again oxidation, and finally into sodium salt.
Общее описание
Sulforhodamine G is an ambipolar fluorescent dye that is used as an acceptor dye for organic electronics. It is a water soluble and hydrophilic dye that shows an absorption peak at a wavelength of 529 nm.
Staining Procedures
The specimen is treated for 5 seconds in a 1 mM freshly prepared and filtered solution of sulforhodamine G before sectioning. Hand sections are mounted in paraffin oil for fluorescence microscopy. The distribution of induced fluorescence corresponds to the water content of the tissue. For details, see Watt et al. (1996).
