Nodal antibodies are essential tools in developmental biology and cancer research, targeting the Nodal protein, a member of the TGF-β (transforming growth factor-beta) superfamily. Nodal plays a critical role in embryonic development, particularly in establishing left-right asymmetry, mesoderm formation, and maintaining pluripotency in embryonic stem cells. It signals through a Smad2/3-dependent pathway, often in coordination with co-receptors like Cripto-1 and Lefty, which regulate its activity and spatial distribution. Dysregulation of Nodal has been implicated in cancers, where its re-expression in tumors correlates with aggressiveness, metastasis, and stem-like properties.
Antibodies against Nodal are used to detect its expression, localization, and interaction partners in various experimental models. They enable techniques like Western blotting, immunohistochemistry, and immunofluorescence, helping researchers study Nodal's role in cellular processes and disease. Commercial Nodal antibodies are typically raised in hosts like rabbits or mice, targeting specific epitopes (e.g., mature peptide regions), and are validated for applications in human, mouse, or other model organisms. Challenges include ensuring specificity due to Nodal's low abundance and structural homology with other TGF-β members. Recent studies also explore Nodal inhibition using neutralizing antibodies as a therapeutic strategy in cancer, highlighting its dual role as both a developmental regulator and an oncogenic factor.
