  • PROTEIN PROBE COMPOUNDS, COMPOSITIONS, AND METHODS
    Publication number: 20080026478
    Abstract: Coumarine/chinolone and Martina-type compounds, compositions, and method of using the compounds and compositions for protein detection, assay, quantitation, etc. are disclosed. The composition, also referred to as a dye, has enhanced sensitivity over commercially available protein stains, and may be used to stain proteins in solution, proteins separated on gels, proteins transferred to solid supports, etc.

  • PROTEIN DETECTION AND QUANTITATION USING HYDROXYQUINOLONE DYES
    Publication number: 20070281360
    Abstract: A hydroxyquinolone compound formulated as a fluorescent dye for protein detection, assay, quantitation, etc. The hydroxyquinolone compound may be modified, for example, by adding or removing sulfate groups, changing hydrocarbon chain lengths, etc. to result in more desirable properties such as enhanced binding to basic proteins, enhanced solubility, etc. The dye has enhanced sensitivity over commercially available protein stains, and may be used to stain proteins in solution, proteins separated on gels, proteins transferred to solid supports, etc. Methods of using the dyes are also disclosed.

  • Direct Detection of Biomolecules in a Gel
    Publication number: 20060252108
    Abstract: A method for detecting a target biomolecule directly in a polyacrylamide gel in which it has been separated from other substances. Prior to binding the target to a probe and while the target biomolecule remains in the gel, the gel is immersed in a water miscible aqueous extracting medium containing a base to shrink the gel by at least about ten percent, and then the gel is washed with water to restore the gel to substantially its original size.

  • Direct detection of biomolecules in polyacrylamide gel improvement comprising shrinking and rehydrating of gel prior to labeling
    Patent number: 7112411
    Abstract: An improved method for detecting a target biomolecule directly in a polyacrylamide gel in which it has been separated from other substances. The improvement resides in, prior to binding the target to a probe and while the target biomolecule remains in the gel, (1) immersing the gel in a water miscible, aqueous extracting medium to shrink the gel by at least about ten percent and then (2) washing the gel with water to restore the gel to substantially its original size.

  • Coated surfaces with high capacity for capturing target molecules
    Patent number: 6638728
    Abstract: New protein coated surfaces, which have a high capacity for capturing target molecules, thus yielding assays with enhanced sensitivity, are disclosed. Surfaces prepared according to the present invention contain a coating consisting essentially of streptavidin, avidin or “NeutrAvidin” in polymeric form, wherein polymerization has been controlled to an extent such that the polymer is predominantly dimers, trimers and tetramers of the native molecule.
