Proteomics refers to the study of proteins particularly their structure, characterization and function. Some of the methods patented are given below.
Patent no: 6,800,449 titled ‘High throughput functional proteomics’ with the abstract: A method is disclosed which provides a high throughput method for assigning plausible functions to unknown sequence entries in a particular database. The method was used herein to identify lectin proteins which can be found in specific tissues of the rice plant.
Patent no: 7,052,843 titled ‘Transcription-based assay for identification of post-translational modification and its application in proteomics’ with the abstract: The present invention relates to a method for detecting the post-translational modification of a target protein by a post translational modifier polypeptide molecule; a method for screening a candidate protein for E3 ligase activity; a method of screening a test compound for the ability to regulate the post-translational modification of a target protein by a post-translational modifier polypeptide molecule; and a method for the large-scale detection of candidate target proteins of post-translational modification by a modifier polypeptide molecule. The present invention also relates to a kit for determining whether a test protein is post-translationally modified by a modifier polypeptide molecule; a kit for screening a test compound for the ability to regulate the post-translational modification of a target protein by a post-translational modifier peptide molecule, and another kit for determining whether a test protein is post-translationally modified by a modifier polypeptide molecule.
Patent no: 7,115,371 titled ‘Rapid, sensitive and quantitative methods for tissue and cell-based proteomics via consecutive addition of quantifiable extenders’ with the abstract: Methods, systems and kits are provided for detecting and quantifying multiple immunogens in a sample via consecutive addition of quantifiable extenders to immunogen bound complexes of immunogen binding agent attached to a DNA containing an RNA polymerase promoter.
Patent no: 6,974,528 titled ‘High performance wide bore electrophoresis’ with the abstract: Methods, apparatus and systems are provided for efficient separation of various small and large molecules, especially biomolecules such as proteins, nucleic acids and polysaccharides. In particular, an electrophoresis apparatus is employed in a wide bore electrophoresis of samples in larger amounts than those in conventional capillary electrophoresis. The electrophoresis apparatus comprises: an electrophoresis chamber comprising a cathode, an anode and a housing; and a separation chamber positioned within the housing and comprising an inlet end, an outlet end, and one or more cooling capillaries positioned inside the separation chamber such that the longitudinal axis of at least one of the cooling capillaries is parallel to the direction of electric current flow from the anode to the cathode, wherein the end of the cooling capillary (or capillaries) is adapted to be coupled to a cooling device that allows cooling medium to pass through the cooling capillary. Electrophoresis systems incorporated with cooling mechanism can utilize wide bore separation tubes and tolerate much higher electric current than that in conventional CE systems. The apparatus can be used to separate and analyze a wide variety of molecules in an automatic, high throughput, and high performance manner. By using the apparatus, methods and systems, large amounts of biomolecules such as proteins can be separated with high resolution and in their native states. Samples separated by this system should be sufficient for many post-separation analyses by other techniques, such as mass spectrometry and crystallography. These features are especially advantageous in building and mining databases of biomolecules in functional genomics, structural genomics and proteomics in the pos
