Patent number: 6586240Abstract: A method for visualizing the location and movement of a specific RNA of interest in a living cell, in real time, is disclosed. The method includes the following steps: (a) providing a DNA encoding the RNA, which RNA includes a protein-binding site; (b) providing a nucleic acid encoding a fusion protein, which fusion protein comprises a fluorescent domain and an RNA-binding domain; (c) introducing the DNA encoding the RNA, and the nucleic acid encoding the fusion protein, into a eukaryotic cell so that the DNA encoding the RNA and the nucleic acid encoding the fusion protein are expressed in the cell; and (d) detecting fluorescence outside the nucleus or inside the nucleus of the cell, with the fluorescence being from the fusion protein bound to the RNA. In some embodiments, the fusion protein also includes an intracellular localization domain.Type: GrantFiled: September 6, 2000Date of Patent: July 1, 2003Assignee: Albert Einstein College of Medicine of Yeshiva UniversityInventors: Robert H.

Patent number: 6242184Abstract: Improved methodologies for in-situ hybridization and non-isotopic detection of nucleic acid sequences are provided which offer major increases of resolution, sensitivity, and simplicity unavailable in previously known techniques. The methodology is able to detect even a single-copy of a specific nucleic acid of interest under controlled conditions regardless of whether these are DNA or RNA sequences; or whether the nucleic acid sequence of interest is localized in the chromosomes, nucleus, or cytoplasm of a cell. The methods employ a variety of non-isotopic labels and detection means for rapid and reliable assays. The invention is also provided in kit form for use in the clinical/diagnostic laboratory such that a relatively unskilled person can accurately and reproducibly detect even a single-copy of a specific nucleic acid of interest.Type: GrantFiled: February 25, 1999Date of Patent: June 5, 2001Assignee: University of MassachusettsInventors: Robert H. Singer, Jeanne Bentley Lawrence, Carol Villnave Johnson

Patent number: 5827660Abstract: Disclosed are methods for removing autofluorescence background from microscopic images or from flow cytometer measurements. The microscopic images can be fluorescent in situ hybridization images or images of living cells. The methods involve the steps of: (1) detecting fluorescence from a cell before "uncaging" a caged fluorochrome label on a probe; (2) uncaging the fluorochrome; (3) detecting fluorescence from the cell; and (4) subtracting fluorescence detected before uncaging from fluorescence detected after uncaging. Also disclosed is a method for tracking the movement of a target molecule in a living cell. Also disclosed is a fluorochrome-uncaging flow cytometer. The fluorochrome-uncaging flow cytometer includes a first fluorescence excitation light beam, an uncaging light beam, a second fluorescence excitation light beam, an electronic data system, a first photodetector operably linked to the electronic data system, and a second photodetector operably linked to the electronic data system.Type: GrantFiled: August 9, 1996Date of Patent: October 27, 1998Assignee: University of MassachusettsInventors: Robert H.

Patent number: 4888278Abstract: Improved methodologies for in-situ hybridization and detection of hybridized nucleic acid sequences in cell cultures and tissue sections are provided which offer an increase of speed, sensitivity, and simplicity unavailable in previously known techniques. The invention detects specific nucleic acids of interest, particularly RNA sequences, within cells and tissues utilizing DNA of a particular size as a probe to find those sequences which are held substantially in common between the cell or tissue and the probe. The cells are fixed preferably in paraformaldehyde and then hybridized using a hybridization fluid for not less than 10 minutes but not substantially more than 24 hours. A variety of identifying labels are attached to the probe which permit quick and rapid detection via measurement of radioactive isotope decay or by colorimetric detection of enzymatic reaction products.Type: GrantFiled: October 13, 1988Date of Patent: December 19, 1989Assignee: University of Massachusetts Medical CenterInventors: Robert H.
