Biotin is an essential vitamin that binds streptavidin or avidin with high affinity and specificity. As biotin is a small molecule that can be linked to proteins without affecting their biological activity, biotinylation is applied widely in biochemical assays. In our laboratory, IgM enzyme immuno assays (EIAs) of µ-capture format have been set up against many viruses, using as antigen biotinyl...
Antibodies raised against human milk fat globule (HMFG 1 and 2) and carcinoembryonic antigen were used in an immunoperoxidase technique to differentiate mesothelioma, carcinoma, and benign, reactive mesothelium. Sixteen mesotheliomas, 27 lung carcinomas, and 13 specimens of reactive mesothelium were examined. Staining for carcinoembryonic antigen was not seen in reactive mesothelium or mesothel...
addition of n-butyl nitrite to isolated rat hepatocytes caused an immediate glutathione depletion followed by an inhibition of mitochondrial respiration, inhi- bition of glycolysis and atp depletion. at cytotoxic butyl nitrite concentrations, lipid peroxidation occurred before the plasma membrane was disrupted. cytochrome p-450 inhibitors inhibited peroxynitrite formation and prevented ...
Chicken interleukin-17 (chIL-17) gene was previously characterized through cloning from a chicken intestinal expressed sequence tag (EST) cDNA library. To further investigate the biological properties of chIL-17, six monoclonal antibodies (mAbs) against a bacterially expressed chIL-17 recombinant protein were produced and their binding specificities characterized. Antibodies which were initiall...

Monoclonal antibodies reactive with hairy cell leukemia were developed to aid in the diagnosis of this subtype of B cell chronic lymphocytic leukemia and to gain better insight into the origin of hairy cells. Three antibodies were found to be of value in the diagnosis of hairy cell leukemia. Antibody B-ly 2 can be considered a pan-B cell reagent and generally reacts similar to CD22 antibodies. ...
The present study was conducted to characterize the nature and pattern of serum and secretory antibody responses to N. gonorrhoeae by haemagglutination inhibition, opsonization, and immunofluorescence techniques in male and female patients with different clinical manifestations of gonorrhoea. Most male patients with acute gonococcal infection developed serum IgG and, less frequently, IgM antibo...
Background: Flat urothelial lesions comprise a spectrum of morphologic changes ranging from reactive atypia to carcinoma in situ (CIS). Urothelial dysplasia and CIS are associated with the recurrence and progression of urothelial carcinoma. Distinguishing CIS and dysplasia from reactive atypia based on histolopathogical features alone is often difficult. Using different immunohistochemical mark...
Normal and immune sera from various animal species were fractionated on columns of Sepharose covalently coupled with the glycoprotein fetuin. Elution of the material bound to fetuin yielded low but reproducible amounts of protein, ranging from 0.02 to 0.2% of the protein mass of the input sera. This material has been identified by immunoelectrophoresis in agar and by zone electrophoresis on cel...
