Abstract:
The present invention provides methods and compositions for labeling, separating and analyzing proteins, particularly a specific protein of interest within a cell lysate or in a mixture of proteins. The proteins are labeled with an amine reactive or thiol reactive fluorescent dye, or an amine reactive fluorogenic reagent that becomes fluorescent upon reacting to amine groups located on the protein. Following the labeling step, the proteins within the mixture can be separated and analyzed. In a further embodiment, a tag binding fluorogenic reagent that can bind to a tag on a tagged protein is added to specifically label the protein of interest.
Abstract:
The present teachings provide methods, devices, systems, and materials for performing electrophoresis in an automated fashion. The electrophoresis system may simultaneously image gel during an electrophoresis run. In some embodiments, the electrophoresis system may analyze an imaged gel during or after electrophoresis. The device may comprise a gel processing system, a gel illumination system, an image capture system, and an image analysis all housed within a housing.
Abstract:
The present invention provides systems, devices, apparatuses and methods for automated bioprocessing. Examples of protocols and bioprocessing procedures suitable for the present invention include but are not limited to immunoprecipitation, chromatin immunoprecipitation, recombinant protein isolation, nucleic acid separation and isolation, protein labeling, separation and isolation, cell separation and isolation, food safety analysis and automatic bead based separation. In some embodiments, the invention provides automated systems, automated devices, automated cartridges and automated methods of western blot processing. Other embodiments include automated systems, automated devices, automated cartridges and automated methods for separation, preparation and purification of nucleic acids, such as DNA or RNA or fragments thereof, including plasmid DNA, genomic DNA, bacterial DNA, viral DNA and any other DNA, and for automated systems, automated devices, automated cartridges and automated methods for processing, separation and purification of proteins, peptides and the like.
Abstract:
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.
