 Methods and compositions for sensitive and rapid, functional identification of genomic polynucleotides and secondary screening capabilities

Details
Inventors: Whitney, Michael A.;
Assignee: Aurora Biosciences Corporation (San Diego, CA)
Primary Examiner: Fredman; Jeffrey
Assistant Examiner:
Attorney, Agent or Firm: Fish & Richardson P.C.

The invention provides for a methods and compositions for identifying proteins or compounds that directly or indirectly modulate a genomic polynucleotide and methods for identifying active genomic polynucleotides. Generally, the method comprises inserting a BL (beta-lactamase) expression construct into an eukaryotic genome, usually non-yeast, contained in at least one living cell, contacting the cell with a predetermined concentration of a modulator, and detecting BL activity in the cell.

DETAILED DESCRIPTION OF THE INVENTION Definitions Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
Generally, the nomenclature used herein and the laboratory procedures in cell culture, molecular genetics, and nucleic acid chemistry and hybridization described below are those well known and commonly employed in the art.
Standard techniques are used for recombinant nucleic acid methods, polynucleotide synthesis, and microbial culture and transformation (e.
g.
, electroporation, lipofection).
Generally, enzymatic reactions and purification steps are performed according to the manufacturer's specifications.
The techniques and procedures are generally performed according to conventional methods in the art and various general references (see generally, Sambrook et al.
Molecular Cloning: A Laboratory Manual, 2d ed.
(1989) Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.
Y.
, which is incorporated herein by reference) which are provided throughout this document.
The nomenclature used herein and the laboratory procedures in analytical chemistry, organic synthetic chemistry, and pharmaceutical formulation described below are those well known and commonly employed in the art.
Standard techniques are used for chemical syntheses, chemical analyses, pharmaceutical formulation and delivery, and treatment of patients.
As employed throughout the disclosure, the following terms, unless otherwise indicated, shall be understood to have the following meanings: "Fluorescent donor moiety" refers to the radical of a fluorogenic compound which can absorb energy and is capable of transferring the energy to another fluorogenic molecule or part of a compound.
Suitable donor fluorogenic molecules include, but are not limited to, coumarins and related dyes xanthene dyes such as fluoresceins, rhodols, and rhodamines, resorufins, cyanine dyes, bimanes, acridines, isoindoles, dansyl dyes, aminophthalic hydrazides such as luminol and isoluminol derivatives, aminophthalimides, aminonaphthalimides, aminobenzofurans, aminoquinolines, dicyanohydroquinones, and europium and terbium complexes and related compounds
