Anti-ISL1 Antibody

Offered through Antibodies.com as part of the primary antibody range, this rabbit polyclonal reagent targets the ISL1 (Islet-1) transcription factor and is supplied in a 50 µl format. It is raised against a recombinant human ISL1 immunogen and affinity-purified using that immunogen, yielding a preparation at 1.0 mg/mL in unconjugated form. The host species is rabbit and the clonality is polyclonal, making it suitable for standard immunodetection workflows across multiple species. According to the manufacturer, the antibody recognizes endogenous levels of total ISL1 and has been validated for Western blot (WB) and immunofluorescence (IF) applications, with broader reactivity claimed for human, mouse and rat samples. The buffer composition is documented on the supplier page: phosphate-buffered saline without Mg²⁺ and Ca²⁺, adjusted to pH 7.4 and supplemented with 150 mM NaCl, 0.02% sodium azide as preservative, and 50% glycerol for cold storage. This formulation is consistent with typical storage at -20 °C, with the recommendation to aliquot to avoid repeated freeze-thaw cycles. As a research-use-only reagent, it is intended for laboratory investigation of ISL1 expression in developmental biology, pancreatic islet studies, motor neuron research and cardiac lineage work, where ISL1 serves as a key marker. The product ships from the Antibodies.com warehouse and is priced within the catalogue's mid-range polyclonal tier, reflecting the affinity purification step and the cross-species validation profile.
