Horseradish peroxidase was incorporated in a kieselguhr membrane. The electron-transfer process of the enzyme was examined by cyclic voltammetry. It was observed that the electron-transfer reactivity of horseradish peroxidase was greatly enhanced, and that direct electrochemistry was accordingly feasible. Using the merits of the direct electron-transfer reactivity of horseradish peroxidase and ...
We made 202 examinations on specimens from 78 patients, to evaluate the application of horseradish peroxidase-labeled antisera as compared to fluorescein-labeled material in a clinical immunology laboratory. Various circulating and tissue-fixed antibodies were identified by both techniques. The horseradish peroxidase technique can be substituted for the fluorescein isothiocyanate method for the...
Background and aims: The exact nature of the epithelial barrier defect in Crohn’s disease remains to be elucidated. Previously we showed increased permeability to proteins in ileal Crohn’s disease. Our aims were to study if this barrier defect (a) involves endocytotic uptake of antigens and (b) is related to low grade inflammation not detectable by histology. Methods: Macroscopically normal seg...
