A reproducible and sensitive one-step enzyme immunoassay (EIA) was developed to determine total tissue-type plasminogen activator (t-PA) antigen in plasma. The EIA comprises two monoclonal catching antibodies and a polyclonal (goat) tagging antibody conjugated with horseradish peroxidase. There is an equal reactivity towards the several physiological t-PA… (More)
A one-step enzyme immunoassay (EIA) has been developed for plasminogen activator inhibitor-1 (PAI-1) antigen. The assay is based on polyclonal antibodies, which were found to be slightly more reactive with tissue-type plasminogen activator (t-PA)/PAI-1 complexes and latent PAI-1 than with active PAI-1. To correct this, active PAI-1 is converted to… (More)
Soluble fibrin is considered as a molecular marker for intravascular fibrin formation, and impending thrombotic events. Most of the existing assays are less suitable for routine clinical applications and their specificity may be limited. We have developed a sandwich-type EIA with a fibrin-specific MoAb described by us before (Proc Natl Acad Sci 1989; 86:… (More)
An assay has been developed which enables the simultaneous determination of active free PAI-1 and t-PA/PAI-1 complexes in plasma samples. Test plasma is divided into two subsamples in which (a) active PAI-1 is quantitatively converted to t-PA/PAI-1 complexes, and (b) conversion of PAI-1 to t-PA/PAI-1 complexes is prevented. The amounts of t-PA/PAI-1 complex… (More)
A high intake of beta-carotene has been associated with a decreased risk for cardiovascular disease. To evaluate whether beta-carotene may exert a protective effect through an impact on haemostasis a randomized, placebo-controlled trial was conducted in male smokers (n = 149) using 20 mg/day beta-carotene for 14 weeks. For comparisons, haemostatic… (More)
Let X be a simplicial, quasi-projective toric variety. The goal of this article is to show that the groups G i (X) of K-theory of coherent sheaves and K i (X) of vector bundles are rationally isomorphic. The case i = 0 answers a question of Brion and Vergne.
