  • Patent number: 8278045
    Abstract: This invention relates to non-radioactive markers that facilitate the detection and analysis of nascent proteins translated within cellular or cell-free translation systems. Nascent proteins containing these markers can be rapidly and efficiently detected, isolated and analyzed without the handling and disposal problems associated with radioactive reagents. Preferred markers are dipyrrometheneboron difluoride (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene)dyes.

  • Patent number: 8148062
    Abstract: The invention is directed to methods for the non-radioactive labeling, detection, quantitation and isolation of nascent proteins translated in a cellular or cell-free translation system. tRNA molecules are misaminoacylated with non-radioactive markers which may be non-native amino acids, amino acid analogs or derivatives, or substances recognized by the protein synthesizing machinery. Markers may comprise cleavable moieties, detectable labels, reporter properties wherein markers incorporated into protein can be distinguished from unincorporated markers, or coupling agents which facilitate the detection and isolation of nascent protein from other components of the translation system. The invention also comprises proteins prepared using misaminoacylated tRNAs which can be utilized in pharmaceutical compositions for the treatment of diseases and disorders in humans and other mammals, and kits which may used for the detection of diseases and disorders.

  • Patent number: 7807407
    Abstract: This invention relates to the detection and analysis by mass spec of nascent proteins, and in particular truncated proteins, translated within cellular or cell-free translation systems. N-terminal and C-terminal epitopes introduced into these nascent proteins permit rapid and efficient isolation, as well as a mass difference.

  • Patent number: 7595198
    Abstract: This invention relates to agents and conjugates that can be used to detect and isolate target components from complex mixtures such as proteins and protein fragments from biological samples from in vivo and in vitro sources. Agents comprise a detectable group bound to a photoreactive group. Conjugates comprise agents coupled to substrates by covalent bounds which can be selectively cleaved with the administration of electromagnetic radiation. Targets substances labeled with detectable molecules can be easily identified and separated from a heterologous mixture of substances. Exposure of the conjugate to radiation releases the target in a functional form and completely unaltered. Using photocleavable molecular precursors as the conjugates, label can be incorporated into macromolecules, the nascent macromolecules isolated and the label completely removed.

  • Patent number: 7534861
    Abstract: A hybrid polypeptide composed of a p53 epitope peptide and a desired functional protein are produced by recombinant DNA techniques. A DNA expression vector is constructed that includes segments of DNA coding for the epitope peptide and the desired functional protein. An optional linking portion is contemplated. The linking portion of the epitope peptide is cleavable at a specific amino acid residue adjacent the functional protein by use of a sequence specific proteolytic enzyme or chemical proteolytic agent. The hybrid polypeptide expressed by the host cells transformed by the cloning vector is removed therefrom and purified by affinity chromatography techniques by use of an immobilized antibody specific to the antigenic portion of the epitope peptide. The protein is then cleaved from the isolated hybrid polypeptide with an appropriate proteolic enzyme or chemical agent, thereby releasing the mature functional protein in highly purified, highly active state.
