Anti-Internexin alpha (Alpha-Inx) Antibody
Our Anti-Internexin alpha (Alpha-Inx) rabbit polyclonal primary antibody detects cat, human, mouse, other mammals, and rat Internexin alpha (Alpha-Inx), and is whole serum. It is validated for use in ICC, IHC-Frozen, WB.

![Left: Detection of alpha-internexin expression (green) in rat cerebellum by Immunohistochemistry. The rabbit antibody to alpha-internexin was used at 1:2,000 dilution, and section was co-stained with chicken antibody to GFAP (C-1373-50, red, 1:5,000). Blue: DAPI nuclear stain. IHC Method: Following transcardial perfusion with 4% paraformaldehyde, brain was post-fixed for 24 hours, cut to 45 um, and free-floating sections were stained. The alpha-internexin antibody selectively stains axons and dendrites of neuronal cells, in particular Purkinje cells and parallel fibers the axons of granule cells. The GFAP antibody labels network of glial cells, such as astrocytes in the granule cell layer and white matter and Bergmann glia in the molecular layer.

The alpha-internexin protein from different species is known to vary slightly in molecular weight as determined by SDS-PAGE.](http://www.antibodiesinc.com/cdn/shop/files/r-1379-50-ihc-wb_120x120.jpg?v=1759274402)
Mixed neuron-glial cultures stained with Rabbit polyclonal antibody to Internexin alpha R-1379-50 (red) and Chicken polyclonal antibody to peripherin C-1399-50 (green). The alpha internexin antibody stains numerous axonal and dendritic profiles in these cultures, while Peripherin antibody binds to only a subset of neurons.

Product Details
Internexin alpha (Alpha-Inx)
Neurofilaments can be defined as the intermediate or 10 nm 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.
