Development of a quantitative thyroid-stimulating hormone assay system for a benchtop digital ELISA desktop analyzer.

Regular checkups for thyroid-stimulating hormone (TSH) levels are essential for the diagnosis of thyroid disease. The enzyme-linked immunosorbent assay (ELISA) technique is a standard method for detecting TSH in the serum or plasma of hospitalized patients. A recently developed next-generation ELISA, the digital immunoassay (d-IA), has facilitated detection of molecules with ultra-high-sensitivity.

Development of an automated chemiluminescent immunoassay for cancer antigen 72-4 and the evaluation of its analytical performance.

Objectives: Cancer antigen (CA) 72-4 assay is widely used for monitoring gastric and ovarian cancers. The antigen is a mucin-like, tumor-associated glycoprotein known as TAG-72. It has been identified and characterized using two different monoclonal antibodies, CC49 and B72.

Novel multiple assessment of hepatocellular drug disposition in a single packaged procedure.

Unlabelled: Better prediction of drug disposition prior to the clinical trial is critical for the efficient development of new drugs. The purpose of this study is to develop a novel multiple assessment methodology of hepatocellular drug disposition from drug uptake to efflux including biliary and basolateral excretion, in a single packaged procedure. We started a sandwich culture using rat primary hepatocytes.

Viscoelastic and light scattering studies on thermally induced sol to gel phase transition in fish myosin solutions.

Viscoelastic (VE) and dynamic light scattering (DLS) analyses of fish (white croaker) myosin solutions were performed at myosin concentrations of 30 mg/mL for VE and 0.1 mg/mL for DLS at 0.6M KCl and pH 7.

The accumulation of arc (an immediate early gene) mRNA by the inhibition of protein synthesis.

Arc (activity-regulated cytoskeleton-associated protein) gene is one of the neuron-specific immediate early genes induced by neural activity. The regulation of Arc gene expression is unknown. We found that Arc mRNA is expressed constitutively in L929 cells, a mouse fibroblast cell line, and was, not transiently, increased by the calcium ionophore A23187.
