Monoclonal antibodies were raised against human placental soluble E-cadherins and used in an immunoenzymometric assay to detect soluble E-cadherins in biological fluids. The E-cadherin assay was… (More)

Soluble P-selectin is present in normal circulation and its plasma level is elevated in patients with thrombotic thrombocytopenic purpura and haemolytic uraemic syndrome.

Two hybridoma cell lines producing monoclonal antibodies WGA-1 and PL7-6, reactive only with thrombin-stimulated human platelet have been established. Both these antibodies were investigated for… (More)

Urinary fibronectin fragments (a potential tumor marker) measured by immunoenzymometric assay with domain-specific monoclonal antibodies.

We found that urinary fibronectin (UFN) in cancer patients was almost all fragmented and consisted mainly of the cell-binding domain. We developed a two-site immunoenzymometric assay for UFN, using… (More)

Isolation and characterization of two monoclonal antibodies that recognize remote epitopes on the cell-binding domain of human fibronectin.

OBJECTIVE E-cadherin is a major cell-to-cell adhesion molecule, of which the ectodomain is cleaved from epithelial cells to yield a soluble form after the pathological alteration of the alveolar… (More)

Immunoenzymometric analysis for plasma von Willebrand factor degradation in diabetes mellitus using monoclonal antibodies recognizing protease-sensitive sites.
