    Abstract: A reagent and kit are disclosed for determining if a patient is hypercoagulable, hypocoagulable or normal. The test involves providing a test sample from the patient and initiating coagulation in the sample in the presence of an activator, which is added to the sample in an amount which will result in intrinsic tenase-dependent fibrin. Then the formation of the intrinsic tenase-dependent fibrin polymerization is monitored over time so as to derive a time-dependent profile, with the results of the fibrin polymerization monitoring determining whether the patient is hypercoagulable, normal or hypocoagulable. The coagulation activator is added in an amount that triggers a thrombin explosion that is dependent on the propagation phase and amplification pathways. In this way, a single assay can assess the hemostatic potential of a sample.

    Abstract: The horseshoe crab, Carcinoscorpius rotundicauda Factor C cDNA (CrFC21) has been cloned into a shuttle baculoviral vector and another vector suitable for expression in insect cells. The recombinant baculoviral DNA was then transfected into the insect cells for expression of recombinant Factor C. Recombinant Factor C was found to be immunoreactive and is capable of binding both free and bound/immobilized lipid A. It is enzymatically active when triggered by LPS. The rFC is probably of the two-chain form, being cleaved into the heavy and light chains after activation by Gram negative bacterial endotoxin. As low as 0.01 pg (0.001 ng/ml) of LPS was detectable by the rFC, thus, indicating its potentials as a novel generation of “limulus amoebocyte lysate.

  • Publication number: 20030124705
    Abstract: Novel conjugates of glycosaminoglycans, particularly heparin and dermatan sulfate, and amine containing species and therapeutic uses thereof are described. In particular, mild methods of conjugating heparins to proteins, such as antithrombin III and heparin cofactor II, which provide covalent conjugates which retain maximal biological activity are described. Uses of these conjugates to prevent thrombogenesis, in particular in lung airways, such as found in infant and adult respiratory distress syndrome, and on surfaces in contact with blood are also described.
