Data Examples
Detection of Human/Mouse/Rat alpha ‑Internexin by Western Blot. Western blot shows lysates of SH‑SY5Y human neuroblastoma cell line, human, mouse, and rat liver tissue. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat alpha ‑Internexin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4844) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for alpha-Internexin at approximately 66 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 2.

Background: alpha-Internexin

Alpha-Internexin ( alpha -INX; also 66 kDa neurofilament protein (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. Human alpha -INX is 499 amino acids (aa) in length. It has a predicted MW of 55 kDa, but runs anomalously at 66 kDa in SDS-PAGE. 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 shares more that 96% aa identity with mouse, canine and rat alpha -INX.
