    摘要: An apparatus includes a body portion that defines a reservoir and a set of substantially flexible capillaries. The set of substantially flexible capillaries are fixedly coupled to the body portion and in fluid communication with the reservoir. A connector is configured to be coupled to the body portion to be in fluid communication with the reservoir and the set of substantially flexible capillaries. The connector is further configured to be coupled to a vacuum source. The apparatus is arranged such that at least a part of the body portion is electrically conductive. Methods for separating and detecting an analyte from a biological sample with the apparatus are also provided. For example, methods for separating and detecting one or more proteins from a cellular lysate or a purified protein are also provided.

    摘要: Gels, such as polyacrylamide gels, are provided that include linear polyacrylamide in the stacking gel. Native gels that include linear polyacrylamide in the stacker can be used to separate biomolecular complexes, such as protein complexes. Gel cassettes in which the gap width between front and back plates does not vary by more than 5% at the upper edge of the cassette are also provided. The gel cassettes can be used for electrophoretic separation of proteins and protein complexes on native gels, such as native gels that include linear polyacrylamide in the stacker. The native gels can have multiple wells for electrophoresing at least one sample and/or at least one molecular weight standard.

    摘要: An optical fiber (500) illuminates the bore (520) of a capillary tube (515) that is used for separating chemicals by capillary electrophoresis (CE). The fiber terminates in either two sloped regions (525) and a curved region (530) or two sloped regions (705) and a flat region (700). Light from these regions is focused on the bore of the capillary tube. Since the fiber is sized to illuminate the core of a CE capillary, it is larger than fibers used in telecommunications and its sloped regions are at angles that would be unsuitable for use in telecommunications. The relatively large diameter of the capillary permits efficient use of a light source (905).
