Monoclonal Mouse Ascites B IH
The mammalian apurinic/apyrimidinic endonuclease
(APE/ref-1) is responsible for the repair of AP sites in DNA. In addition, this enzyme functions as a redox factor facilitating the DNA binding capability of FOS, JUN, NfkB, HIF-1 alpha, Pax-5, Pax-8 and other transcription factors. APE/ref-1 has also been shown to control p53 activity through redox alteration. APE is linked to apoptosis, associated with thioredoxin, and altered levels of APE/ref-1 have been found in some cancers. APE appears to form a unique link between the DNA base excision pathway, oxidative signaling, transcription regulation, cancer and cell-cycle control.
Catalog #A2298-74
ApplicationsSuitable for use in Western Blot and Immunohistochemistry.
Other applications not tested.
Recommended DilutionWestern Blot: > 1:2000 Detects single 37kD band using ECL. Immunohistochemistry (frozen and paraffin fixed sections and cytospin preps): > 1:5000, it can be competitively inhibited from recognizing APE/ref-1 antigen in tissues using APE/ref-1 protein.
Optimal dilution determined by the researcher.
Positive ControlHeLa whole cell extract
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
