Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser165/166 of human desmoplakin protein. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

Western Blotting

Western blot analysis of extracts from A-431 and Calu-3 cells, untreated or treated with calf intestinal phosphatase (CIP) and λ phosphatase, using Phospho-Desmoplakin (Ser165/166) Antibody.未处理或经过牛小肠碱性磷酸酶(CIP)和λ磷酸酶处理的A-431和Calu-3细胞提取物进行western blot分析,使用Phospho-Desmoplakin (Ser165/166)抗体进行实验。


Desmosomes are a class of intracellular junction that tightly link adjacent cells in mechanically stressed tissues such as the epithelium and myocardium (1). They derive their characteristic strength from the protein Desmoplakin, which acts as a tether by binding the cytoplasmic component of the Desmosome at it’s N-terminus (2) while its C-terminus is anchored to the intermediate-filament cytoskeleton (3). This association mitigates the impact of mechanical forces on the desmosome by distributing them throughout the cytoskeleton and tissue (4). Desmoplakin is essential for normal desmosomal adhesion (5); defects can result in pathologies that include cardiomyopathy (6), keratoderma (7), or the skin blistering disease Epidermolysis bullosa (8).
