Mouse Monoclonal Antibody to Peripherin Cat# MCA-7C5
Description
The MCA-7C5 antibody was made against full length recombinant rat peripherin expressed in and purified from E. coli. It recognizes rat and mouse peripherin but does not recognize the human, pig or bovine proteins. The antibody works well for western blotting and for IF, ICC and IHC on rodent material (for IHC see data under "Additional Info" tab).We also manufacture a rabbit and chicken polyclonal antibodies to the same immunogen, RPCA-Peri and CPCA-Peri. Finally we have made a widely used mouse monoclonal antibody to peripherin which recognizes this protein in human, rodent and many other species, MCA-8G2.

Peripherin is a ~57kDa 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 as a major cytoskeletal protein in rat pheochromacytoma PC12 cells (2,3). Peripherin is expressed in certain neuroendocrine cells and in the insulin producing cells of the pancreas, and autoantibodies to peripherin may be seen in diabetes mellitus (4). It is also prominently expressed in certain tumors and in the ballooned axons typical of amyotrophic lateral sclerosis (5,6). Different classes of neuron and nerve fiber may be identified based on their expression of peripherin, NF-L and other markers (e.g. 7). There are multiple transcripts from the single peripherin gene, some of which encode proteins which produce proteins unable to form intermediate filaments and which induce the formation of pathological inclusions (8,9). Note that the intermediate filament subunit peripherin (HGNC PRPH) is completely unrelated to peripherin/RDS (HGNC PRPH2), a retinal protein belonging to the tetraspanin family.
Chromogenic immunostaining of a 4% PFA fixed paraffin embedded rat brain stem section with mouse mAb to peripherin, MCA-7C5, dilution 1:1,000, detected with DAB (brown) using the Vector Labs ImmPRESS method and reagents with citra buffer retrieval. Hematoxylin (blue) was used as the counterstain. In brain, MCA-7C5 labels the cytoplasm of a specific subset of neurons within the brain stem expected to have projections towards the periphery. This antibody performs well in testing with 4% PFA fixed tissues but was not tested for immunohistochemistry on NBF fixed paraffin sections. MCA-7C5 is our recommended clone for immunostaining of rat tissue. It does not cross react with the human protein. Mouse select image for larger view.
