Development of immunohistochemistry for detecting fluvoxamine in rat tissues using newly prepared monoclonal antibody: its precise localization in small intestine, kidney, and liver of rats.
A monoclonal antibody (mAb) was produced against a fluvoxamine (FLV)-bovine serum albumin conjugate that was specific to both the conjugate and free form of FLV. The mAb enabled us to develop an immunohistochemistry (IHC) method for pharmacokinetic analysis of FLV at the cell and tissue levels. We demonstrated that IHC can be used to detect the localization of FLV in the small intestine, kidney, and liver 1 h after drug administration at the cell and tissue levels. Protease digestion is an important factor for obtaining appropriate IHC staining results for localization of drugs. In this study, precise FLV localization could be determined with only 1 h of protease digestion in the kidneys, but in the small intestine and liver, the staining results with two digestive conditions had to be merged. IHC provided new findings, such as (1) nerve cells are likely to uptake more FLV than other cells and tissues; (2) the ability of reabsorption and secretion in the kidney varies depending on the site, and the amount of FLV in the primary urine is regulated downstream of the proximal tubule S3 segment; and (3) some of the FLV is excreted in the bile.
期刊介绍：
Medical Molecular Morphology is an international forum for researchers in both basic and clinical medicine to present and discuss new research on the structural mechanisms and the processes of health and disease at the molecular level. The structures of molecules, organelles, cells, tissues, and organs determine their normal function. Disease is thus best understood in terms of structural changes in these different levels of biological organization, especially in molecules and molecular interactions as well as the cellular localization of chemical components. Medical Molecular Morphology welcomes articles on basic or clinical research in the fields of cell biology, molecular biology, and medical, veterinary, and dental sciences using techniques for structural research such as electron microscopy, confocal laser scanning microscopy, enzyme histochemistry, immunohistochemistry, radioautography, X-ray microanalysis, and in situ hybridization.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
