Used in biomedical research to quantify Human Gap Junction Proteins (connexins) in tissue samples and cell lysates. Enables study of intercellular communication, particularly in cardiac, neural, and epithelial tissues where gap junctions regulate signal transmission. Applied in disease research including arrhythmias, neurodegenerative disorders, and cancer to assess connexin expression changes. Supports drug development by monitoring protein levels in response to therapeutic agents. Commonly used in academic labs, pharmaceutical research, and clinical diagnostics for high-throughput screening and biomarker validation.
