Islet-1 (ISL1) antibody is a valuable tool in biomedical research, primarily targeting the ISL1 transcription factor, a member of the LIM/homeodomain protein family. Discovered in the 1990s, ISL1 plays critical roles in embryonic development, particularly in the differentiation and survival of pancreatic islet cells, motor neurons, and cardiac progenitor cells. It is named for its initial identification in pancreatic islets, where it regulates insulin gene expression and β-cell maturation. Beyond the pancreas, ISL1 is essential for nervous system development, including retinal ganglion cells and spinal motor neurons, as well as heart formation.
The ISL1 antibody is widely used to identify and study cell populations dependent on ISL1 activity. In immunostaining, it helps visualize ISL1-expressing cells in tissues like the pancreas, brain, and heart, aiding research on diabetes, neurodevelopmental disorders, and congenital heart defects. It also serves as a marker in stem cell research to assess the differentiation of pluripotent cells into insulin-producing β-cells or cardiac lineages. Commercial ISL1 antibodies are typically raised in rabbits or mice, targeting specific epitopes of the protein. Validation methods include Western blotting, immunohistochemistry, and knockout controls to ensure specificity. Its applications span developmental biology, disease modeling, and regenerative medicine, underscoring its importance in understanding organogenesis and related pathologies.
