Patent number: 6702134Abstract: A closure system useful for storing fluids under cold storage conditions. The closure system includes cap and container components which combine to form a dual sealing system. The container has a generally cylindrical side wall, a closed bottom end, and an open top end having an inner beveled lip depending from an annular top rim. The cap has a generally circular top wall from which inner and outer skirts depend. The outer skirt is adapted to grip the open top end of the container. The inner skirt includes an outer surface having a lower seal bead and an upper beveled portion mated with the beveled lip. When the cap is fitted onto the container, the seal bead contacts an inner surface of the container and the upper beveled portion and the beveled lip are engaged in an interference fit, thereby impeding the loss of fluid from the closure system under cold storage conditions.Type: GrantFiled: September 27, 2002Date of Patent: March 9, 2004Assignee: Gen-Probe IncorporatedInventors: Robert F. Scalese, Daniel L. Kacian

Patent number: 6663353Abstract: A sensor for detecting contact of a fluid delivery probe with a fluid surface and for detecting fluid flow through the probe includes a first electrode disposed along a fluid flow path of the probe upstream from a distal tip of the probe and a second electrode longitudinally spaced and electrically isolated from the first electrode and disposed at the distal tip of the probe. An oscillating signal is transmitted through the first electrode, and at least a portion of the signal is received through the second electrode. Through changes in the received signal due to the distal tip of the probe coming into contact with a fluid surface or due to fluid flow through the conduit between the first and second electrodes, fluid surface contact and fluid flow can be detected. A pressure sensor can be employed to monitor internal fluid pressure within the fluid conduit of the fluid delivery probe as a secondary, redundant mechanism for detecting fluid flow through the conduit.Type: GrantFiled: August 8, 2002Date of Patent: December 16, 2003Assignee: Gen-Probe IncorporatedInventors: James H. Lipscomb, Larry Jurik, Bernard Katz, Michael J. Keating, Stone Klengler, John J. Kotlarik, Mieczyslaw Wroblewski

Patent number: 6245519Abstract: The present invention features compositions and methods that are useful for storing labeled detection probes and detecting whether a target nucleic acid sequence is present in a sample. Preferred compositions are made up of a detection probe containing a label susceptible to a chemical or enzymatic alteration and a protection probe that protects the label from alteration and/or decreases the ability of the detection probe to inhibit nucleic acid amplification. Such compositions can be used, for example, to stabilize a detection probe label and to prevent a detection probe from hybridizing prematurely to amplified or target nucleic acid.Type: GrantFiled: February 11, 2000Date of Patent: June 12, 2001Assignee: Gen-Probe IncorporatedInventors: Steven T.
