Publication number: 20050009013Abstract: 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.Type: ApplicationFiled: March 20, 2001Publication date: January 13, 2005Inventors: Kenneth Rothschild, Sadanand Gite, Jerzy Olejnik

Publication number: 20040138413Abstract: 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.Type: ApplicationFiled: January 10, 2003Publication date: July 15, 2004Applicant: AmberGen, Inc.Inventors: Kenneth J. Rothschild, Sadanand Gite, Jerzy Olejnik, Mark Lim

Publication number: 20040053217Abstract: This invention relates to agents and conjugates that can be used to detect and isolate target components from complex mixtures such as nucleic acids from biological samples, cells from bodily fluids, and nascent proteins from translation reactions. Agents comprise a detectable moiety bound to a photoreactive moiety. 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.Type: ApplicationFiled: March 25, 2003Publication date: March 18, 2004Applicant: The Trustees of Boston UniversityInventors: Kenneth J. Rothschild, Sanjay M. Sonar, Jerzy Olejnik

Publication number: 20040033514Abstract: 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 utflized in pharmaceutical compositions for the treatment of diseases and disorders in humans and other maninials, and kits which may be used for the detection of diseases and disorders.Type: ApplicationFiled: March 27, 2003Publication date: February 19, 2004Applicant: The Trustees of Boston UniversityInventors: Kenneth J.
