Product Overview
This rabbit polyclonal antibody detects alpha-internexin (gene INA) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 55.4 kDa, and the supplier reports an observed band at about 62–66 kDa.
Alpha-internexin (encoded by INA) is a type IV neuronal intermediate filament protein expressed early in neuronal development. It can assemble on its own or co-assemble with neurofilament proteins such as NEFL to form the axonal cytoskeleton, and it is used as a neuronal marker in neurobiology and neuropathology studies.
