Product Summary for alpha-Internexin Antibody

Immunogen

Recombinant rat alpha-internexin expressed in and purified from E. coli. Accession # P23565

Reactivity Notes

Reactivity assumed based on 100% sequence homology to a wide variety of mammalian species.

Specificity

Specific for endogenous levels of the ~66 kDa alpha-Internexin protein. Minor bands at ~150 kDa are probably covalent dimers and bands at ~50 kDa represent alpha-internexin breakdown products.

Marker

Immature Neuronal Marker

Clonality

Polyclonal

Host

Chicken

Isotype

IgY

Theoretical MW

66 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Description

Recommended that the undiluted antibody be aliquoted into smaller working volumes (10-30 uL/vial depending on usage).

Background: alpha-Internexin

Alpha-internexin is a Class IV intermediate filament originally discovered as it co-purifies with other neurofilament subunits (1). Alpha-internexin is related to but distinct from the better known neurofilament triplet proteins, NF-L, NF-M and NF-H, having similar protein sequence motifs and a similar intron organization. It is expressed only in neurons and in large amounts early in neuronal development, but is down-regulated in many neurons as development proceeds. 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, recent studies show a marked up-regulation of alpha-internexin during neuronal regeneration (2). The use of antibodies to this protein in the study of brain tumors has not been examined to date, but is likely to be of interest. Recently Cairns et al. used this antibody to show that alpha-internexin is an abundant component of the inclusions of neurofilament inclusion body disease (NFID), a serious human neurodegenerative disorder (3,4). The antibody was also used to confirm the presence of circulating auto-antibodies to alpha-internexin in the sera of some patients with endocrine autoimmunity, as well as in some normal individuals (5).
