  • Patent number: 7081228
    Abstract: A sample aliquot pipette tip (SAT) includes a pipette tip and a sample aliquot cup. The pipette tip is collapsible. The sample aliquot cup is arranged above the pipette tip and is fluidly coupled with the pipette tip. The SAT works in concert with a tip aliquot support (TAS). The TAS may include a channel for accepting a collapsed pipette tip of an SAT, a support for accommodating a sample aliquot cup of a SAT and a constricted passage arranged between the support and the channel. As an SAT is inserted into a TAS, the constricted passage of the TAS collapses the pipette tip of the SAT. The collapsed pipette tip of the SAT is then received by the channel of the TAS. When the SAT is fully inserted into the TAS, the support of the TAS accommodates the sample aliquot cup of the SAT.

  • Patent number: 6174734
    Abstract: The invention features a novel method of assaying glycated hemoglobin (GHb) in a sample using a capture molecule that binds GHb and hemoglobin (Hb), and detecting bound GHb with a molecule that distinguishes GHb from non-glycated hemoglobin (Hb). The molecule used to distinguish GHb from Hb may be an antibody. The assay and antibodies of the invention are useful for the evaluation of GHb in disease states such as diabetes.

  • Patent number: 5281662
    Abstract: Disclosed is a treated material including a base material such as an extrudate, a woven fabric, or unwoven fibers, a disperse dye-type molecule such as a dye or antibiotic dispersed within and non-covalently adhered to the base material, and a molecule-of-interest immobilized on the base material by way of a reactive group on the disperse dye-type molecule. Also disclosed are methods of producing the treated material.

  • Patent number: 5167960
    Abstract: Disclosed is a biocompatible, thromboresistant substance useful for implantable and extracorpeoreal devices in contact with the vascular system, and methods for producing the same. The biocompatible, thromboresistant substance comprises a synthetic, biocompatible material, at least one biocompatible base coat layer adhered to at least one surface of the material, and a thrombogenesis inhibitor immobilized on the base coat layer via a component capable of binding the inhibitor. The thrombogenesis inhibitor is hirudin, or an active analog or fragment thereof.

  • Patent number: 5126140
    Abstract: Disclosed is a biocompatible, thromboresistant substance useful for implantable and extracorporeal devices in contact with the vascular system, and methods for producing the same. The biocompatible, thromboresistant substance comprises a synthetic, biocompatible material, at least one biocompatible base coat layer adhered to at least one surface of the material, and the thrombogenesis inhibitor thrombomodulin immobilized on the base coat layer via a component capable of binding the inhibitor without affecting its thrombogenesis-inhibiting activity.

  • Patent number: 5112615
    Abstract: Disclosed is a soluble, biocompatible, pharmacological agent for inhibiting thrombin generation and thrombus formation, and methods for producing the same. The pharmacological agent or conjugate includes a soluble, biocompatible carrier and a thrombogenesis inhibitor immobilized thereto via the carrier which binds the inhibitor. The thrombogenesis inhibitor is hirudin, or an active analog or active fragment thereof. The thrombogenesis inhibitor may be bound to the carrier via a bifunctional cross-linking reagent.

  • Patent number: 5019393
    Abstract: Disclosed is a biocompatible, thromboresistant substance useful for implantable and extracorporeal devices in contact with the vascular system, and methods for producing the same. The biocompatible, thromboresistant substance comprises a synthetic, biocompatible material, at least one biocompatible base coat layer adhered to at least one surface of the material, and a thrombogenesis inhibitor immobilized on the base coat layer via a component capable of binding the inhibitor. The thrombogenesis inhibitor is streptokinase, urokinase, tissue plasminogen activator, ATPase, 5'-nucleotidase, and active fragments and active analogs thereof.
