    Claudin-19 Antibody (H-4) is a mouse monoclonal IgG2b antibody that detects claudin-19 in mouse, rat, and human samples through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). Claudin-19 is a crucial multi-pass membrane protein consisting of 224 amino acids and is part of the claudin family, which plays a vital role in forming and maintaining tight junctions between cells. These tight junctions regulate paracellular transport and maintain epithelial and endothelial barrier integrity. Claudin-19 is expressed in specific tissues and exists in two isoforms due to alternative splicing, which may influence functional properties and protein interactions. Defects in the gene encoding claudin-19 can lead to hypomagnesemia renal with ocular involvement (HOMGO), a serious renal disorder characterized by low magnesium levels, high calcium excretion, and kidney calcification, highlighting claudin-19′s importance in maintaining electrolyte balance and overall renal health. Anti-claudin-19 antibody (H-4) serves as an invaluable tool for researchers studying tight junction dynamics and related pathologies.

    Can claudin-19 (H-4): sc-365968 monoclonal antibody be used to stain formalin-fixed, paraffin-embedded (FFPE) tissue sections?

    Asked by: Germaine
    Thank you for your question. Yes, claudin-19 (H-4): sc-365968 has been validated for use in IHC with paraffin-embedded sections. We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
