Patents by Inventor Klaus Buecker

Klaus Buecker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for separating non-HDLs from HDLs, and determining, HDL cholesterol
    Patent number: 6214570
    Abstract: The subject matter of the application is a method for the separation of non-HDL lipoproteins from biological fluids in a carrier through which liquids can flow. The carrier contains a precipitating agent for non-high density lipoproteins (non-HDLs).
    Type: Grant
    Filed: July 14, 1998
    Date of Patent: April 10, 2001
    Assignee: Roche Diagnostics GmbH
    Inventors: Walter Rittersdorf, Ulfert Deneke, Gerhard Hiller, Hartmut Merdes, Klaus Buecker, Uwe Goebbert
  • Method for the determination of HDL cholesterol by means of a rapid diagnostic agent with an integrated fractionating step
    Patent number: 6171849
    Abstract: An apparatus comprising a first porous carrier and a second porous carrier for evaluating biological fluid samples is disclosed. The apparatus is used for separating non high density lipoprotein (non-HDL) from a lipoprotein in a body sample and for determining high density lipoprotein (HDL) cholesterol in a HDL and non high density lipoprotein (non-HDL) in a body sample.

  • Method for separating non-high density lipoproteins from lipoprotein containing body fluid samples
    Patent number: 5786164
    Abstract: The invention relates to a method useful in separating non-high density lipoproteins, referred to as "non-HDLs", from biological fluids containing them. A porous carrier is provided which contains a non-HDL precipitating agent. One need only contact the sample of interest to the carrier for one minute or less, after which the precipitated non-HDL-s are no longer present in the sample being tested. The applications of the method include the ability to determine high density lipoproteins in the sample without interference from non-HDLs.
