Anthrax infection is initiated by the inhalation, ingestion, or cutaneous contact with Bacillus anthracis endospores.
B.
anthracis produces three polypeptides that comprise the anthrax toxin: protective antigen (PA), lethal factor (LF), and edema factor (EF) (1,2 for review).
PA binds to two related proteins on the cell surface; these are termed tumor epithelial marker 8 (TEM8)/anthrax toxin receptor (ATR) (3) and capillary morphogenesis protein 2 (CMG2) (4), although it is still unclear which is physiologically relevant.
Following PA binding to its receptor, PA is cleaved into two fragments by a furin-like protease.
The bound fragment binds both LF and EF; the resulting complex is then endocytosed which allows the translocation of LF and EF into the cytoplasm (5).
LF is the primary toxin of anthrax and functions as a highly specific protease that cleaves members of the mitogen-activated protein kinase kinase (MAPKK) family near their amino terminus, interfering with MAPK signaling and inducing apoptosis (6).
Applications:Can be used for the detection of Anthrax LF protein in ELISA.
It will detect 10 ng of free peptide at 1ug/ml.
Storage and Stability:May be stored at 4°C for short-term only.
For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%).
Store at -20°C or colder.
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.
