Desmin – MMab

For In Vitro Diagnostic Use

Desmin is a type of intermediate filament found near the Z line in sarcomeres. Both vimentin and desmin are characteristics of mesenchymal cells. Desmin antibody detects a protein that is expressed by cells of normal smooth, skeletal and cardiac muscles. Light microscopy studies of desmin suggests that it is primarily located at or near the periphery of Z lines in striated muscle fibrils. In smooth muscle, Desmin interconnects cytoplasmic dense bodies with membranebound dense plaques. Desmin antibody reacts with Leiomyomas, Rhabdomyomas, and Perivascular cells of Glomus Tumors of the skin (if they are of myogenic nature). This antibody is used to demonstrate the myogenic components/derivation of tumors.

Antibody Type Mouse Monoclonal
Clone D33
Isotype IgG1/K
Reactivity Paraffin, Frozen

Control Skeletal Muscle

Desmin antibody is a mouse monoclonal antibody derived from cell culture supernatant that is concentrated, dialyzed, filter sterilized and diluted in buffer pH 7.5, containing BSA and sodium azide as a preservative.
