Detection of Human alpha -Internexin by Western Blot. Western blot shows lysates of human cortex tissue. PVDF membrane was probed with 2 µg/mL of Mouse Anti‑Human alpha -Internexin Monoclonal Antibody (Catalog # MAB4844) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for alpha -Internexin at approximately 50-70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

alpha -Internexin ( alpha -Inx; also NF-66) is a 66 kDa member of the intermediate filament (IF) protein family. It was the first of two molecules named for its presumed interaction with cytoskeletal proteins. alpha -Inx is one of four Class IV neuronal IF proteins. It both self-assembles and complexes with NF-L, H and M in select cortical and cerebellar neurons. alpha -Inx contains one DNA-binding region (aa 10‑92), a poly‑Glu segment (aa 449‑454) and three serine phosphorylation sites (Ser72/335/496). There is one 494 aa alternative splice form that shows multiple short sequence aa substitutions in the first 200 amino acids. Over aa 230‑450, human alpha -Inx shows more that 96% aa identity with mouse, canine and rat alpha -Inx.
