Abstract: Small molecule fluorescent probes for established drug targets such as nucleic acids including DNA and RNA has been developed and disclosed herein. These nucleic acid probes bind to multiple DNA and RNA structures, and to sites crucial for nucleic acid function, such as DNA and RNA major grooves. Displacement of the probes by other binders such as small molecule compounds and/or proteins illicits a fluorescence change in the probe that once detected and analyzed provide binding information of these other binders of interest. Similarly, changes in fluorescence upon binding of the probes to nucleic acid have been applied to screen nucleic acid of different sequence and conformation. The nucleic acid probes and method of uses disclosed herein are advantageously suitable for high-through put screening of libraries of small molecule compounds, proteins, and nucleic acids.

The target binding regions comprise nucleic acid sequences that allow them to hybridize to adjacent regions on the target nucleic acid. The stem regions have nucleic acid sequences that are complementary to each other and the capture regions each comprise a sequence that when positioned adjacent to one another produce a combined nucleic acid sequence that is complementary to a portion of an oligonucleotide bound to a solid support.

Abstract: The present invention relates to a method of biological labeling that occurs via a free radical chain reaction. The labeling occurs due to deposition of a detectable reporter molecule from a media comprising a substance comprising at least two moieties of a peroxidase enzyme substrate (termed herein ‘cross-linker’) in a target site comprising peroxidase activity and a biological marker. The labeling reaction described herein may generally be used to detect targets in a host of experimental schemes for detecting and visualizing a biological or chemical target, including immunohistochemistry (IHC), in situ hybridization (ISH), antibody-based staining methods such as ELISA, Southern, Northern, and Western blotting, and others.
Abstract: The invention provides methods of detecting an analyte by multi-stage mass spectrometry with improved S/N ratio. An analyte is labeled with a positively-charged mass tag to form a precursor ion that leads by anchimeric assistance to a greatly enhanced, analyte-characteristic first product ion that can, in turn, lead to a greatly enhanced, analyte-characteristic second product ion in a mass spectrometer. Either a three stage mass spectrometer (true MS3) or a two-stage mass spectrometer (MS2) operated in a pseudo MS3 mode can be used. The precursor ion is split via an anchimeric-assisted reaction to form a first product ion, which in turn can be fragmented to form the second product ion. The methods offer extreme ultrasensitivity, at the low amol level. The invention also provides anchimeric mass tags for use in the methods. A wide variety of previously undetectable analytes of biological or environmental origin can be detected and quantified.

The PNA probe may be attached to beads (26) which are initially embedded in a wax body (17) and are released during the heating so that they are free to move and come into contact with the PNA probe and target DNA. After binding has occurred, the beads are magnetically attracted back into a pocket (16) along with the wax (17), which is allowed to solidify before they are removed from the reaction vessel.
