Neurofilaments can be defined as the intermediate or 10nm diameter filaments found in neuronal cells. They are composed a mixture of subunits which often includes the neurofilament triplet proteins, NF-L, NF-M and NF-H. Neurofilaments may also include peripherin, alpha-internexin, nestin and in some cases vimentin. Alpha-internexin is a ~66 kDa Class IV intermediate filament subunit expressed in large amounts early in neuronal development, but is downregulated in many neurons as development procedes. Many classes of mature neurons contain alpha-internexin in addition to NF-L, NF-M and NF-H. In some mature neurons alpha-internexin is the only neurofilament subunit expressed. Antibodies to alpha-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 alpha-internexin means its presence is an early and convenient diagnostic feature of neuronal progenitors cells and other cell committed to the neuronal lineage.
The specificity of this antibody has been confirmed by WB. This antibody is specific for the 64-66 kDa alpha-internexin protein. Molecular weight will depend on species. The antibody reacts with alpha-internexin from multiple species including human, mouse, rat and feline. It is expected to react with other mammalian species as well because of protein sequence homology.
Application Information:
Western Blotting (WB) and Immunocytochemistry (IC). A dilution of 1:5,000 - 10,000 is recommended for WB. A dilution of 1:500-1,000 is recommended for IC. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.
