Detection of Human XPE/DDB2 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line and U2OS human osteosarcoma cell line. PVDF membrane was probed with 0.5 µg/mL of Human XPE/DDB2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3297) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for XPE/DDB2 at approximately 45 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 1.

Xeroderma Pigmentosum complementation group E (XPE) patients are defective in a heterodimer of damage-specific DNA-binding activity (DDB1/DDB2). DDB2 is a 48 kDa protein upregulated in cells exposed to ultraviolet light. XP patients exhibit hypersensitivity to ultraviolet light and have a heightened incidence of skin cancer.
