Identification of Plectin in Different Human Cell Types and Immunolocalization at Epithelial Basal Cell Surface Membranes

Identification of Plectin in Different Human Cell Types and Immunolocalization at Epithelial Basal Cell Surface Membranes

G Wiche et al. Exp Cell Res.

Abstract

The occurrence of plectin in various human tissues and cell lines was investigated using immunofluorescence microscopy and antibody gel overlay/immunoblotting techniques. Plectin was identified in all tissues and cell lines tested, namely placenta, kidney, cornea, foreskin and eyelid skin, skin fibroblasts, monocytes, keratinocytes and HeLa cells. In frozen sections of cornea and skin, plectin was found to be enriched at epithelial basal cell surface membranes. Consequently, antibodies to plectin could serve as a tool in the classification of mechanobullous diseases.
