Top Left: Coomassie Brilliant Blue stained SDS-PAGE gel of various recombinant proteins based on the human sequences. His-tagged human peripherin isotype I was expressed in E. coli strain BL21 and purified using an N-terminal His-tag by immobilized metal affinity chromatography. 1µg of protein was run on each lane, and the lane indicated with “Peri” contains the peripherin protein. The other lanes show recombinant His-tagged α-internexin (α-int), vimentin (Vim) and neurofilament NF-L (NF-L) as indicated. Protein molecular weight standards are in the first lane and molecular weights are as indicated. The recombinant proteins all include an N-terminal His-tag, in each case adding about 5kDa to the size of the native human protein.

$300.00 – $2,000.00
Peripherin is a ~57 kDa intermediate filament subunit found initially in sensory neurons of the peripheral nervous systems, which gives the protein its name. Peripherin was later found in some sensory and other neurons of the central nervous system, in rat pheochromacytoma PC12 cells, in certain neuroendocrine tumors and in the insulin producing cells of the pancreas. Peripherin belongs to the Class III family of intermediate filament subunits and is often co-expressed with vimentin and neurofilament subunits.

Peripherin is a ~57 kDa intermediate filament subunit found initially in sensory neurons of the peripheral nervous systems, which gives the protein its name (1). Subsequently, peripherin was found in some sensory and other neurons of the central nervous system and also in rat pheochromacytoma PC12 cells (2,3). 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 also 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
A cDNA encoding full length human Peripherin was inserted into a eukaryotic expression vector which adds an N-terminal in frame His-tag. This was transformed into E. coli and recombinant protein was purified in 6M urea using immobilized metal affinity chromatography. Purified protein was diluted to 1 mg/mL and is supplied in 6M urea.
