Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro623 of human XRCC1 protein.

Background

The X-ray repair cross-complementing protein 1 (XRCC1) is a DNA repair protein important in both single strand break repair and base excision repair following damage from ionizing radiation and alkylating agents (1). XRCC1 acts as a scaffold protein to coordinate DNA abasic site repair through interaction with several other repair proteins (2). At least eight XRCC1 protein partners have been identified, including the polynucleotide kinase PNK (3), DNA ligase III (4,5), poly (ADP-ribose) polymerase (6), and PCNA (7). Mutations and polymorphisms in the XRCC1 gene serve as diagnostic markers and are associated with elevated risk of various forms of cancers (8).

XRCC1 (E4A3V) XP® Rabbit mAb

Western Blotting Image 1: XRCC1 (E4A3V) XP® Rabbit mAb Expand Image
Western blot analysis of extracts from control HCT 116 cells (lane 1) or CRISPR/Cas9 XRCC1 knockdown (KD) HCT 116 cells (lane 2) using XRCC1 (E4A3V) XP® Rabbit mAb (upper) or GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). The reduction of signal in the XRCC1 KD HCT 116 cells confirms specificity of the antibody for XRCC1.
