| titleOfInvention | Automated electrophoresis and fluorescence detection apparatus and method |
| abstract | Improved detection methods and apparatus which may be used individually or in various combinations enhance the ability of the electrophoresis apparatus to detect fluorophore-labeled materials in short periods of time. One such apparatus comprises a housing adapted to receive an electrophoresis gel holder; an excitation source of electromagnetic radiation having a frequency effective to induce emission of electromagnetic radiation from the fluorophore; a plurality of optical fibers for delivering electromagnetic radiation from the excitation source to a linear array of excitation/detection sites on the gel holder, optical switching means for sequentially directing electromagnetic radiation into one of several pre-defined groups of the optical fibers; detection means such as a photomultiplier tube, or an array of photomultiplier tubes for detecting emission from the fluorophore induced by a radiation from the excitation source; and means for correlating a detected emission with the switching of the excitation electromagnetic radiation such that a given emission may be linked with the excitation/detection site being irradiated. For example, the optical switching means may alternate between directing radiation from the source into every other optical fiber, or may provide radiation in rotation to every third or fourth fiber. Alternatively, a spot array generation grating can be used for dividing an incident beam of coherent radiation into an array of excitation beamlets and directing each excitation beamlet to an excitation/detection site on the electrophoresis gel. Light emitting diode disposed to deliver excitation energy to an array of excitation/detection sites may also be used. This latter form of the apparatus is particularly advantageous due to the low costs of light emitting diodes (LEDs) compared to coherent light sources (e.g. lasers). |
