Detection of Human XPA by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 0.5 µg/mL of Human XPA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3416) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for XPA at approximately 40 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 5.

Background: XPA

The Xeroderma Pigmentosum A (XPA) protein is a component of a large complex that binds to damaged DNA to facilitate nucleotide excision repair (NER). XPA binds in a complex with Replication Protein A (RPA), XPG, and TFIIH (a subcomplex of the RNA polymerase II transcription initiation complex). XPA is thought to stabilize the binding of RPA to DNA, and thus aid in specific recognition of the damaged base. Because of their NER defect, XP patients exhibit hypersensitivity to ultraviolet light and have a heightened incidence of skin cancer.
