Größe

£655.00

SKU:: B0003-05L5
Reinheit:: Purified by immunoaffinity chromatography.
Lagerbedingungen:: 4°C (-20°C Glycerol)
Hersteller:: United States Biological
Host:: Rabbit
Immunogen:: Synthetic peptide corresponding to 16 amino acids near the carboxy-terminus of the Anthrax lethal factor protein (Genbank accession no. P15917).
Format:: Supplied as a liquid in PBS, pH 7.4, 0.02% sodium azide.
Weitere Details:: 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. Other applications not tested. Recommended Dilution: ELISA: 1ug/ml detects 10ng of free peptide Optimal dilution determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, 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.
