Product Overview
This rabbit polyclonal antibody detects desmin in human, mouse and rat samples and is validated for ICC/IF, IHC and Western blot. The predicted molecular weight is 53.5 kDa, and the supplier reports an observed band at about 53 kDa.
Desmin (DES) is the main intermediate filament protein of skeletal, cardiac and smooth muscle. It links neighboring myofibrils at the Z-disks and connects them to the sarcolemma, nucleus and mitochondria, helping muscle cells resist mechanical stress. Desmin is a standard muscle marker, and mutations cause desmin-related myopathies and cardiomyopathies.

Immunogen
Recombinant human Desmin fragment (Met1–Thr304), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 97%.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places desmin in the cytoplasm, cell membrane, nucleus and cell tip. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
