Alpha Internexin Antibody Staining Protocol for Immunohistochemistry

 

Description: Alpha-internexin is a 66kD protein which shares several characteristics with intermediate filament (IF) proteins. In rats, alpha-internexin is often co-purified with intermediate filaments from spinal cord and optic nerve and the protein is axonally transported together with the neurofilament triplet proteins (68, 160 and 200kD) along the length of the optic nerve. Although the distribution of alpha-internexin is similar to the light component neurofilament (68kD), its distribution in rat embryo is far more extensive in the early stages of development.
