Product Overview
Clone 22D49 is a rabbit monoclonal antibody that recognizes desmoplakin (gene DSP) in human and rat samples and is validated for Western blot, ICC/IF and flow cytometry. The predicted molecular weight is 331.8 kDa, and the supplier reports an observed band at about 250 kDa.
Desmoplakin (DSP) is the main plaque protein of desmosomes, anchoring intermediate filaments such as keratins and desmin to cell-cell junctions. It is essential in the skin and the heart, and it is studied in epithelial adhesion, early development and inherited cardiomyopathies and skin disorders.

Immunogen
Synthetic peptide based on the sequence of human desmoplakin.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt places desmoplakin in the cell projection, cell junction, cell membrane and cytoplasm. Tissue expression noted by UniProt (human): Expressed in oral mucosa (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
