Cleavage of amyloid precursor protein (APP) into 40 or 42 amino acid amyloid beta (ab) peptides is a result of the action of two proteases beta- and gamma-secretase. The beta-site APP cleaving enzyme, or BACE1, is a transmembrane aspartic protease that is localized in the Golgi and endosomes. Low levels of BACE1 mRNA are found in most adult tissues with a higher level of expression in pancreas.
Applications
Suitable for use in Immunohistochemistry, Flow Cytometry, Western Blot and Direct ELISA. Other applications not tested.
Recommended Dilutions
Immunohistochemistry: 8ug/ml detects BACE1 in paraffin-embedded human Alzheimer’s brain tissue sections. Flow Cytometry: 25ug/ml; 10ul labels 1-2.5x10e5 cells in a total reaction volume < 200ul. The binding of unlabeled monoclonal antibodies may be visualized by adding 10ul of a 25ug/ml stock solution of a secondary developing reagent such as goat anti-mouse IgG conjugated to a fluorochrome. Western Blot: 2ug/ml detects human BACE1 in cell or tissue extracts under reducing conditions only. Direct ELISA: 0.5-1.0ug/ml. The detection limit is ~1ng/well. Optimal dilutions to be determined by the researcher.
Western Blot Buffers
Blotting Buffer: 25mM Tris, pH 7.4, 0.15M sodium chloride, 0.05% Tween-20 Blocking Solution: 5% nonfat dry milk in Blotting Buffer Antibody Solution: 5% nonfat dry milk in Blotting Buffer
