Aurora Discovery has been awarded US Patent No. 6,861,035, “Multi-well platforms, caddies, lids, and combinations thereof.”
Inventors listed on the patent are Andrew Pham, Peter Coassin, Alec Harootunian, Peter Pham, Harry Stylli, and Roger Tsien.
According to its abstract, the patent protects multi-well platforms, lids, caddies and any combination thereof. The multi-well platforms comprise a plurality of wells that can be of any shape and can be arranged in any ornamental pattern. The lid comprises an area corresponding to the well field. The caddy has a footprint approximately that of a standard 96-well microtiter plate. When the multi-well platform is engaged with the caddy, the wells of the well-field of the multi-well platform are preferably not obscured by the caddy when viewed from the bottom of the combination, the abstract states.
Ramot University Authority for Applied Research & Industrial Development has been awarded US Patent No. 6,861,220, “Genetic screening methods.”
Inventors listed on the patent are Dan Canaani, Arnold Simons, Naomi Dafni, and Iris Dotan.
According to its abstract, the patent protects a method for screening molecules which have a synthetic lethal property when in combination with a gene of interest carrying a non-lethal mutation. The method comprises the steps of: Transfecting a first reporter gene into mammalian cells having a genome comprising a gene of interest which carries a non-lethal mutation, or a genome which is null of the gene of interest; selecting clones stably expressing the first reporter gene; introducing into the cells a survival plasmid comprising a functioning copy of the gene of interest, a second reporter gene, selectable marker, an origin of DNA replication, and a nuclear antigen gene essential for replication of the plasmid within the cells, wherein the survival plasmid is autonomously replicating and spontaneously lost from the cells; growing the cells in the presence of a selection compound which selects for the selectable marker; selecting cell clones stably expressing the second reporter gene and the functioning copy of the gene of interest; removing selection for the selectable marker; and adding molecules destined for screening of their ability to impose selective pressure enforcing retention of the unstable survival plasmid, thus determining survival plasmid retention in cells and identifying a molecule having a synthetic lethal property when in combination with the non-lethal mutated gene of interest, the abstract states.
Cis Bio International has been awarded US Patent No. 6,861,264, “Method of measuring the luminescence emitted in a luminescent assay.”
Inventors listed on the patent are Michel Mabile, Gerard Mathis, Etienne Jean-Pierre Jolu, Dominique Pouyat, and Christophe Dumont.
According to its abstract, the patent protects a method of measuring the luminescence emitted in a luminescent assay, which makes it possible to correct certain perturbations due to the measuring medium. The method comprises employing at least one luminescent tracer compound and a luminescent compound used as an internal reference, which, when exposed to the same excitation wavelength, are capable of emitting at wavelengths 1 and 2 respectively, either by direct luminescence or by the induction of a luminescent emission, and correcting the luminescence measurement emitted at wavelength 2 on the basis of the measurement of the luminescence emitted at wavelength 1. The invention further relates to the use of the method in a homogeneous method of detecting and/or determining an analyte, and to a device for carrying it out.
