Immunogen Rabbit polyclol ATR antibody was raised against a peptide corresponding to 13 amino acids near the center of human ATR (GenBank accession no. NP_444262).
Isotype IgG
Purification Ion exchange chromatography purified.
Background The Anthrax toxin receptor (ATR) was initially discovered as the tumor endothelial marker 8 (TEM8). This protein, which exists in three isoforms (36, 40, and 60 kDa), is highly expressed in tumor vessels as well as in the vasculature of developing embryos, suggesting that it may normally play a role in angiogenesis. However, it also acts as the receptor for anthrax toxin. Following the binding of this protein by the protective antigen (PA) of anthrax, PA is cleaved and heptamerizes to form the binding site for both edema factor (EF) and lethal factor (LF). This complex is then endocytosed by the cell, acidification in endosomes allows the release of EF and LF into the cytoplasm where they interfere with MAPK signaling and induce apoptosis.
Application Notes ATR antibody can be used for detection of ATR by Western blot at 0.5 to 1 µg/ml. (Optimal dilution should be determined by user.) It is human, mouse, and rat reactive. It will recognize all three isoforms. Antibody can also be used for immunohistochemistry and ELISA and might be suited for other applications not tested so far.
Restrictions For Research Use only
Format Liquid
Buffer Antibody is supplied in PBS containing 0.02% sodium azide.
Preservative Sodium azide
Handling Advice Antibody can be stored at 4ºC, stable for one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures. During shipment, small volumes of antibody will occasionally become entrapped in the seal of the product vial. For products with volumes of 200 myl or less, we recommend gently tapping the vial on a hard surface or briefly centrifuging the vial in a tabletop centrifuge to dislodge any liquid in the container’s cap.
Storage 4 °C
Expiry Date 12 months
