Abstract: This invention avoids the need for UV light as well as all the various filters utilized by prior systems while allowing real-time observation and recording of molecules during electophoresis. This invention is a real-time observable electrophoresis system that avoids the use of light filters as the activation of fluorescent dyes is done by LEDs that give off visible light with a certain wavelength, instead of ultraviolet light, which are positioned not on the top or bottom of the electrophoresis gel but on the sides. The background light that is observed in some gels is eliminated by the image analyzing computer software. This system eliminates the need to filter the wavelength of the activating light and enables the observation and recording of the molecules during the entirety of the electrophoresis.

Abstract: The diagnosis of mycobacteria may be made by growing bacteria from clinical samples in a culture media. The culture medium enables rapid detection of mycobacterial growth by changing its color. It also differentiates mycobacterial growth from contamination by changing to a different color when other species of microorganisms grow. Different types of culture media may be obtained by adding antimicrobial drugs to either obtain a medium selective for mycobacteria or a medium for species differentiation or susceptibility testing of drugs.
