Rabbit Polyclonal NKX2-5 Antibody

The NKX2-5 antibody is a crucial tool in cardiovascular research, targeting the NKX2-5 protein, a homeodomain-containing transcription factor essential for heart development. Initially identified in Drosophila as Tinman, its vertebrate homolog NKX2-5 (also called CSX) regulates cardiac progenitor cell differentiation, heart tube formation, and chamber specification. Mutations in the NKX2-5 gene are linked to congenital heart defects (e.g., septal abnormalities, tetralogy of Fallot) and arrhythmias. The antibody, typically generated in rabbits or mice using recombinant NKX2-5 protein fragments, enables detection of NKX2-5 expression in tissues or cells via techniques like Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF). It is widely used to study cardiac development in model organisms (e.g., mice, zebrafish), assess NKX2-5 dysregulation in disease models, and analyze stem cell-derived cardiomyocytes. Researchers also employ it to investigate NKX2-5's role in maintaining adult heart function and its interaction with signaling pathways (e.g., BMP, Notch). Validation includes knockout controls and cross-reactivity checks. Its specificity and reliability make it indispensable for exploring cardiac biology and congenital heart disease mechanisms.
