Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Phe282 of human aprataxin protein.

Background

Aprataxin is a DNA repair protein that resolves DNA lesions (DNA adenylates) caused by abortive ligations in single-strand break repair, double-strand break repair and base excision repair (1). Aprataxin is recruited to sites of DNA damage by PARP1 (2). In the mitochondria, aprataxin and tyrosyl-DNA-phosphodiesterase 1 (TDP1) are required for repair of single strand breaks caused primarily by reactive oxygen species (ROS) (3).
The gene for aprataxin, APTX, is defective in the neurodegenerative disorder oculomotor apraxia type 1 (AOA1)(4). Researchers have shown that levels of aprataxin can predict patient response to irinotecan-based treatments in colorectal cancer (5).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
