Abstract
In a DNA detecting method wherein the fluorescence detection type electrophoresis apparatus is used, Texas Red is employed as a fluorophor which labels a DNA fragment, the He-Ne laser having an emission wavelength of 594 nm is used as an excitation light, the excitation light irradiates the line portion of the gel plate simultaneously, and a resulting linear fluorescent image is collected by a cylindrical lens and photodetected, thereby providing an apparatus featuring a higher sensitivity, a smaller size and a lighter weight than conventional apparatuses.
