A cost-effective multi-channel capillary gel-electrophoresis system for highly efficient, high speed, high throughput, carbohydrate analysis. In one aspect of the present invention, a high-performance capillary electrophoresis analyzer system has been optimized for carbohydrate analysis application. The system uses a multiplexed/time-staggered fluorescence type detection mechanism, with an integrated fiber optic array-based technology and a novel disposable gel-cartridge. Twelve carbohydrate samples are automatically injected, electrophoretically separated, detected and analyzed simultaneously by using a multiple usage and disposable multi-capillary gel-cartridge. Using commercially available labeling agent such as APTS (representing 8-Aminopyrene-1,3,6-trisulfonic acid, trisodium salt) as an indicator, the capillary electrophoresis-based carbohydrate system/analyzer provides high resolving power in 2-15 minutes of separations. The system can hold a total of 96 samples, which can be automatically analyzed within 30-60 minutes. This affordable fiber optic based fluorescence detection system can be used in laboratories for high speed carbohydrate sequencing & screening applications. |
