Compositions comprising a linked acceptor moiety

Detection of nucleic acid using linear beacons

This invention is directed to methods, kits and compositions pertaining to PNA Molecular Beacons. PNA Molecular Beacons comprise self-complementary arm segments and flexible linkages that promote intramolecular or intermolecular interactions. In the absence of a target sequence, PNA Molecular Beacons facilitate efficient energy transfer between the linked donor and acceptor moieties of the probe. Upon hybridization of the probe to a target sequence, there is a measurable change in at least one property of at least one donor or acceptor moiety of the probe which can be used to detect, identify or quantitate the target sequence in a sample.

Methods, kits and compositions pertaining to PNA Molecular Beacons

This invention pertains to solubility enhanced polymers and methods, kits and compositions which enhance the aqueous solubility of said polymers. One set of preferred methods, kits and compositions embody or utilize phosphorous containing synthons and are most useful for modulating the solubility of synthetic nucleic acids and synthetic nucleic acid analogs. A second set of preferred methods, kits and compositions are most useful for modulating the aqueous solubility of peptides, other polyamides and most preferably peptide nucleic acid (PNA) polymers.

Methods for modulating the solubility of synthetic polymers

This invention is directed to methods, kits and compositions pertaining to Linear Beacons. In the absence of a target sequence, Linear Beacons facilitate efficient energy transfer between the donor and acceptor moieties linked to opposite ends of the probe. Upon hybridization of the probe to a target sequence, there is a measurable change in at least one property of at least one donor or acceptor moiety of the probe which can be used to detect, identify or quantitate the target sequence in a sample.

In-situ methods for analyzing target sequences using linear beacons

This invention is directed to methods, kits and compositions which utilize Detection Complexes to detect or identify the presence, absence or quantity of a target molecule in a sample of interest. A Detection Complex comprises at least two component polymers and at least one set of donor and acceptor moieties. To each of at least two component polymers is linked at least one moiety of a set of donor and acceptor moieties, such that formation of the complex facilitates transfer of energy between donor and acceptor moieties of each set in a manner which, in an assay, produces changes in detectable signal which can be correlated with the presence absence of quantity of target sequence and/or target molecule of interest in the sample.

Synthetic polymers and methods, kits or compositions for modulating the solubility of same

A method is disclosed for the preparation of novel PNA synthons compatible with DNA synthetic reagents and instrumentation. Accordingly, the PNA synthons of this invention are particularly suitable for the preparation of PNA-DNA chimeras, among other oligomers. The PNA synthons are designed to have a protecting group strategy which is orthogonal and allows removal of the protecting groups under mild conditions. Generally, an acid labile protected backbone is coupled to a nucleobase side chain moiety to form the PNA synthon. A novel method for synthesizing the acid labile protected backbone also is described. In addition, novel compositions of matter are disclosed.

Methods for automated synthesis of PNA-DNA chimeras and compositions

The invention pertains to compounds and methods for the reversible modification of natural products, biopolymers or synthons for natural products or biopolymers, such as nucleosides, nucleotides, and oligonucleosides. The modification enables one to perform a variety of chemistries on these compounds, yet can be removed to regenerate functional groups on the natural products, biopolymer or synthon of interest.
