Jacobus Henricus Veerkamp 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 linking nucleic acids and/or glycosaminoglycans to polar/hydrophilic materials
    Patent number: 6933379
    Abstract: The invention relates to a method for linking nucleic acid and/or glycosaminoglycan or glycosaminoglycan mimetics to a polar/hydrophilic material, characterized by contacting a nucleic acid and/or glycosaminoglycan and a polar/hydrophilic material with each other in the presence of a solution being 20 to 100 percent saturated with a non-chaotropic salt and removing said solution from the nucleic acid and/or glycosaminoglycan—polar/hydrophilic material.
    Type: Grant
    Filed: March 30, 2001
    Date of Patent: August 23, 2005
    Assignee: Angiomed GmbH & Co. Medizintechnik KG
    Inventors: Antonius H. M. S. M. Van Kuppevelt, Jacobus Henricus Veerkamp, Thiemo Arnim Blank

  • Method for linking negatively charged macrobiomolecules to plastics, resulting linked compositions and microtitre plates incorporating same
    Patent number: 6180769
    Abstract: A method for linking strongly negatively charged biological macromolecules like deoxyribonucleic acid (DNA), ribonucleic acid (RNA) and glycosaminoglycans (GAG) to plastic substrates, comprising contacting the macromolecules and the plastics with a non chaotropic solution containing a salt in an amount of at least 20% of its saturation concentration, or having a pH below the pKa of the charged groups of the macromolecules to be linked. Also disclosed are the products of the method, in particular a microtiter plate with plastic wells coated with the negatively charged non-proteinaceous macrobiomolecules.
