In Western blot, human proteins run at ∽68 kDa, while rat and mouse run lower at ∽66 kDa. Minor bands at ∽150 kDa are probably covalent dimers, and bands at ∽50 kDa represent alpha-internexin breakdown products. Stable at 4°C for at least one year. Mix 1:1 with 100% glycerol and store at -20°C for longer term storage.

Alpha internexin is a Class IV intermediate filament originally discovered as it copurifies with other neurofilament subunits. On SDS-PAGE gels it runs with an apparent molecular weight of 64 to 66 kDa, with some species variability, although the real molecular weight is about 55kDa; as with the other neurofilament subunits the presence of highly negatively charged sequences results in reduction of SDS-PAGE mobility. a-internexin is related to but distinct from the better known neurofilament triplet proteins, NF-L, NF-M and NF-H, having similar protein sequence motifs and a similar intron organization. It is expressed only in neurons and in large amounts early in neuronal development, but is down-regulated in many neurons as development proceeds. Many classes of mature neurons contain a-internexin in addition to NF-L, NF-M and NF-H. In some mature neurons a-internexin is the only neurofilament subunit expressed. Antibodies to a-internexin are therefore unique probes to study and classify neuronal types and follow their processes in sections and in tissue culture. In addition, the very early developmental expression of a-internexin means its presence is an early and convenient diagnostic feature of neuronal progenitors cells and other cells committed to the neuronal lineage. In addition, recent studies show a marked up-regulation of a-internexin during neuronal regeneration.
