Patent number: 10823698Abstract: The invention relates to, among other things, a method for performing electrophoresis with in-situ calibration. The method includes combining a volume of a test sample with a volume or quantity of a calibrating sample to form a final volume, where the volume of the calibrating sample includes a known concentration of a calibrator and the final volume includes a known ratio of test sample to calibrating sample. The method also includes depositing a loading fraction in a receiving well of an electrophoretic gel, in which the loading fraction is a fraction of the final volume, and separating the loading fraction along a common separation lane of the electrophoretic gel such that components of the test sample and the calibrator are separated from one another along the common separation lane.Type: GrantFiled: March 27, 2015Date of Patent: November 3, 2020Assignee: Helena Laboratories CorporationInventors: Philip Guadagno, Erin Summers

Publication number: 20120024416Abstract: A system and method for transferring fluid directly from a container sealed with a closure, to a receptacle. The receptacle includes an aperture and an interior floor. The fluid dispenser has two ends—a first end pierces the closure to establish fluid communication between the interior and exterior of the container and the second end engages the aperture in the receptacle. Relative movement of the receptacle and container toward each other dispenses fluid from the container, through the dispenser, and directly into the receptacle. The second end of the dispenser is precluded from contacting the interior floor of the receptacle to avoid unintentional withdrawal of the fluid from the receptacle.Type: ApplicationFiled: July 29, 2010Publication date: February 2, 2012Applicant: Helena Laboratories CorporationInventors: Tipton Lee Golias, Ronald Allen Mayes

Patent number: 7906183Abstract: A process for making a support for an electrophoretic medium comprising the steps of: applying an agarose coating to a corona treated polymeric film by transferring a layer of agarose solution onto a surface of the corona treated polymeric film. The pH of the agarose solution can be generally maintained between about 8 and about 11 and the concentration of the agarose solution can be generally maintained between about 0.1 and about 0.4% agarose by weight. The agarose powder used to make the agarose solution can be pre-treated by introducing a fresh reducing atmosphere above the agarose powder and exposing the agarose powder to a reducing atmosphere. The reducing atmosphere treatment may be repeated at least three times.Type: GrantFiled: March 30, 2007Date of Patent: March 15, 2011Assignee: Helena Laboratories CorporationInventor: Philip A.

Patent number: 7062077Abstract: Optically scanned data forms an image stored in a computer memory represented as an array having at least two dimensions. The stored image is subjected to virtual scanning. Thus a subset of the array is defined as a portion of the image having first and second dimensions. The value of the subset is derived, the subset is then incremented, and the value of the incremented subset is determined. The steps of incrementing and deriving the value of the incremented subset are repeated. The derived values of the data are compared to a calibrated standard, to create adjusted values of data. The adjusted data values, in the case of electrophoresis, represent the scanned sample which has been subjected to electrophoresis. Thereafter, the adjusted data values can be integrated or otherwise processed.Type: GrantFiled: October 25, 2000Date of Patent: June 13, 2006Assignee: Helena Laboratories CorporationInventor: Charles David Kelley

Patent number: 6939514Abstract: The invention is a method and apparatus to dispense and spread a liquid from a storage container onto a surface. An inventive paddle is attached to an apparatus which is inserted into a storage container, such as a test tube. After dispensing the sample, the storage container is manipulated such that the paddle smears, crushes, or distributes the dispensed sample. Therefore, it is unnecessary to set aside the storage container to perform a smear procedure on a dispensed sample of blood. This increases the safety, speed, and efficiency of the smear procedure, and reduces the risk that the sample will be contaminated. The invention further discloses a method and apparatus for using temperature differential, rather than mechanical force, to safely dispense hazardous biological and chemical samples from a storage container such as a test tube.Type: GrantFiled: November 12, 1996Date of Patent: September 6, 2005Assignee: Helena Laboratories CorporationInventor: Ronald A.
