Detection of disease related genes
First Claim
1. A method, comprising:
- a) providing;
i) nucleic acid comprising a disease-related gene;
ii) PCR primers capable of hybridizing to a portion of said disease-related gene so as to create amplified template;
iii) transcription-translation reagents capable of producing nascent protein or protein fragments from said amplified template, said nascent protein or protein fragments comprising an affinity marker;
iv) an acceptor molecule capable of binding to said affinity marker of said nascent protein;
b) mixing said nucleic acid and said PCR primers under conditions such that said amplified template is created;
c) contacting said amplified template with said transcription-translation reagents under conditions such that nascent protein or protein fragment is produced and said affinity marker is added to said nascent protein or fragment during translation; and
d) reacting said acceptor molecule with said nascent protein or protein fragment.

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