PURPOSE To determine the effects of the proinflammatory cytokines interleukin (IL)-1alpha, IL-1beta, and tumor necrosis factor (TNF)-alpha on neurally mediated lacrimal gland protein secretion and to determine whether the amount of IL-1beta protein is upregulated in inflamed lacrimal glands of the MRL/lpr mouse, a murine model of human Sjögren syndrome. METHODS Lacrimal gland lobules of BALB/...

The aim of this research was to develop a quantitative sandwich-strip ELISA developed on nitrocellulose membrane with anti-H alpha and anti-hCG beta antibodies. detection antibody conjugated horseradish peroxidase, luminol substrate following optimization hCG. Concentration hCG in the BF determined for 101 embryo biopsies (Study 1) 96 2) respectively, results were compared previously recorded m...

OBJECTIVE To describe the clinical characteristics of patients with spontaneous hypothyroidism, the frequency of chronic autoimmune thyroiditis, and the thyroid autoantibody most often associated with this condition in a referral population in Jamaica. METHODS A retrospective study of all cases referred to the author's endocrinology practice from 1995 to 2005 with a diagnosis of spontaneous h...

OBJECTIVE: Diabetes mellitus and thyroid disease are the two common endocrinopathies seen in adult population. Studies to evaluate thyroid disorders in patients with type 2 diabetes are lacking. The aim of this study was to compare prevalence of thyroid dysfunction and autoim-munity in type 2 diabetic patients with age and sex matched non-diabetic control group. MATERIAL AND METHODS: Among pat...

The conjugates of monoclonal antibodies and nanoparticles, including quantum-dot(QD), offer significant advantages over conventional fluorescent probes to image and study biological processes. The extend stability, intense fluorescence and low toxicity of QDs are well suited for biological applications. In the present study, we used QD-conjugated anti-glucose-regulated protein 78(GRP78) antibod...

For the quantitative measurement of pancreatic oncofetal antigen (POA), an enzyme immunoassay for POA has been developed, and is based on the sandwich method using antibody-coupled glass beads and enzyme (peroxidase)-labelled antibody. Serum POA concentrations were increased significantly in patients with pancreatic cancer, but not in those with chronic pancreatitis or other miscellaneous disea...

The bioconjugation of an antibody to an enzymatic reporter such as horseradish peroxidase (HRP) affords an effective mechanism by which immunoassay detection of a target antigen can be achieved. The use of heterobifunctional cross-linkers to covalently link antibodies to HRP provides a simple and convenient means to maintain antibody affinity while imparting a functional reporter used for antig...
