  • Patent number: 9029138
    Abstract: The present invention provides a method for fixing and/or stabilizing a sample, in which the sample is put into a permeable container, the permeable container having an opening, which is pressed into the sample, then a portion of the sample brought into the permeable container in this way is separated from the rest of the sample, and the container filled with the sample in this way is immersed in fixing and/or stabilizing agents and the sample is fixed and/or stabilized.
    Type: Grant
    Filed: August 1, 2008
    Date of Patent: May 12, 2015
    Assignee: Preanalytix GmbH
    Inventors: Daniel Groelz, Christian Lenz, Vera Hollaender, Thomas Rothmann
  • Patent number: 8911680
    Abstract: The invention relates to a system for collecting a biological sample comprising a container having at least one open end, a closure fitting on or in said at least one open end, a holding element connected to said closure and a solid matrix on which said biological sample is deposited, and optionally at least one processing agent, wherein said solid matrix is at least partially transferable into a liquid or dissolved state by changing at least one physico-chemical property of the environment of said matrix without disintegration of the biomolecules comprised in said biological sample deposited on said matrix.
    Type: Grant

  • Publication number: 20110008771
    Abstract: The invention relates to a method for releasing a biological sample from a solid matrix substantially without disintegration of biomolecules comtained in said biological sample by at least partially transferring the solid state of said matrix into a dissolved or liquid state by changing at least one physico-chemical property of the environment of said matrix.

  • Publication number: 20040043505
    Abstract: The present invention is directed to a method and device for collecting and stabilizing a biological sample, particularly a whole blood sample. More specifically, the present invention relates to the use of about 5.6 to about 37.5 mM, preferably about 5.6 to about 10.1 mM, EDTA during collection of the sample and to evacuated fluid sample containers having an amount of EDTA contained therein such that, when the sample is collected, the amount achieved is about 5.6 to about 37.5 mM, preferably about 5.6 to about 10.1 mM, EDTA to stabilize the sample.
