Codon optimized sequence for an antiviral protein

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. The invention also relates to targets isolated with conjugates which may be useful as pharmaceutical agents or compositions that can be administered to humans and other mammals. The invention further relates to kits comprised of agents and conjugates that can be used for the detection of diseases, disorders and individual substances in a complex background of substances.

Bioreactive agents

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 maninials, and kits which may be used for the detection of diseases and disorders.

Detection of disease related genes

This invention relates to agents and conjugates 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. The invention also relates to targets isolated with these conjugates which may be useful as pharmaceutical agents or compositions that can be administered to humans and other mammals.
