ANTI-PERIPHERIN ANTIBODY CLONE 8G2

General description

Peripherin is a ~57kDa intermediate filament subunit found initially in sensory neurons of the peripheral nervous systems. Subsequently it was found in some sensory and other neurons of the central nervous system and also in PC12 cells. Peripherin is also expressed in certain neuroendocrine tumors and in the insulin producing cells of the pancreas. Peripherin belongs to the Class III family of intermediate filament subunits which includes vimentin, glial fibrillary acidic protein (GFAP) and desmin. Antibodies to peripherin can be used in identifying, classifying, and studying neurons throughout the nervous system. Peripherin is also a good diagnostic marker for ballooned axons seen in Lou Gehrig′s disease (Amyotrophic lateral sclerosis) and some neuronally derived tumors. Autoantibodies to peripherin are frequently seen in the sera of patients with diabetes. Peripherin is not related to peripherin/RDS, a protein of the photoreceptor outer membrane mutations of which are causative of certain forms of slow retinal degeneration.

Specificity

Recognizes Peripherin. Strong staining on rat, mouse, human, pig and cow peripherin. Does not work on chicken or other more distantly related species, which may lack peripherin.

Immunogen

Electrophoretically pure trp-E-peripherin fusion protein [Dev. Brain Res. (1990). 57:235-248] containing all but the 4 N-terminal amino acids of rat peripherin. Fusion protein purified from bacterial inclusion bodies by DEAE-cellulose chromatography in 6M urea followed by preparative SDS-PAGE

Application

Anti-Peripherin Antibody, clone 8G2 is an antibody against Peripherin for use in IC, IH & WB.

Immunocytochemistry: 4% PFA fixed cells (5 minutes) or acetone is recommended.

Immunohistochemisty: light PFA fixation is necessary as 8G2 is sensitive to heavy formalin fixation. Antigen recovery is enhanced with 0.1% triton in the block only. 1:25-1:200

Immunoblotting: The antibody is clean and specific for the expected 57kDa band on Western blots.

Optimal working dilutions must be determined by end user.
