Title: Labeled nucleoside polyphosphates
Inventor: KUMAR SHIV
IPC: G01N27/62
Filed: 2002-08-29
Abstract: The present invention describes new compositions of matter in the form of labeled nucleoside polyphosphates with four or more phosphates. In addition compositions of nucleoside polyphosphates with four or more phosphates that are substrates for nucleic acid polymerases with enhanced substrate properti es and methods of using these nucleoside polyphosphates for nucleic acid detection, characterization and quantification are described. The compositio ns provided by this invention include nucleoside polyphosphate, dideoxynucleosi de polyphosphate, or deoxynucleoside polyphosphate analogues which have colorimetric, chemiluminescent, or fluorescent moieties, mass tags or an electrochemical tags attached to the terminal-phosphate. When a nucleic acid polymerase uses this analogue as a substrate, an enzyme-activatable label would be present on the inorganic polyphosphate by-product of phosphoryl transfer. Cleavage of the polyphosphate product of phosphoryl transfer via phosphatase leads to a detectable change in the label attached thereon. When the polymerase assay is performed in the presence of a phosphatase, there is provided a convenient method for real-time monitoring of DNA or RNA synthesi s and detection of a target nucleic acid.

Patent CA-2459598-A1 (CA)
Inventor: LEISING MAURICE B
IPC: B60W30/18
Filed: 2004-03-02
Abstract: A method and arrangement for controlling a continuously variable transmission with improved response time, the continuously variable transmission having a first pulley engagable with an engine and having a second pulley drivingly connected to the first pulley by a belt. The first and second pulleys each have a fixed sheave and a movable sheave, a position of the movable sheaves defining a transmission ratio. The method and arrangement provides for disengaging the engine from the first pulley and increasing the speed of the engine to a target speed, reducing pressure to the movable sheave of the first pulley to a low value, increasing pressure to the movable sheave of the second pulley causing it to rapidly move to a new position thereby changing the transmission ratio to a target transmission ratio, increasing the pressure to the first pulley, and reengaging the engine to the first pulley.
