Used in biomedical research to detect and quantify Human Blocking Protein 2 (CLDN2) levels in cell lysates, tissue extracts, and biological fluids such as serum or plasma. The kit supports studies on tight junction function, epithelial barrier integrity, and diseases involving CLDN2 dysregulation, including certain cancers, inflammatory bowel disease, and liver disorders. It enables researchers to assess CLDN2 expression changes in response to drug treatments, genetic modifications, or disease progression in experimental models. Commonly used in molecular biology and immunology labs for high-throughput screening and biomarker validation.
