Desmin in Human Heart. Desmin was detected in immersion fixed paraffin-embedded sections of human heart using 15 µg/mL Human Desmin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3844) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to the sarcoplasm of cardiomyocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
Desmin in Mouse Skeletal Muscle. Desmin was detected in immersion fixed frozen sections of mouse skeletal muscle using Human Desmin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3844) at 10 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to z-lines.

Desmin is a 53 kDa, muscle-specific molecule that belongs to the intermediate filament superfamily of cytoskeletal proteins. Cytoplasmic Desmin homopolymers form stable filamentous networks that stabilize lateral alignments of myofibrils. Human Desmin is 470 amino acid (aa) peptide. It contains an N-terminal head segment (aa 1-84), multiple coiled regions (aa 109-412), and a tail region (aa 413-470). Single amino acid substitutions and three-amino acid deletions are associated with cardio‑skeletal myopathies. Most mutations affect filament assembly. Desmin is a highly conserved protein. Over the region used as immunogen, human Desmin is 99% identical to the corresponding mouse, canine, and porcine protein sequences.
R&D Systems personnel manually curate a database that contains references using R&D Systems products.
The data collected includes not only links to publications in PubMed,
but also provides information about sample types, species, and experimental conditions.
