Ready-to-use ELISA kits are available for the detection of C76936, an alias of the protein, beta-secretase 1. The official gene symbol is BACE1. The protein, with a mass of 55.8 kDa and length of 501 residues, is reported to be membrane-associated. It is a member of the Peptidase A1 family and may be known by other names, including: beta-site amyloid beta A4 precursor protein-cleaving enzyme, beta-site APP-cleaving enzyme, beta-secretase 1 precursor variant 1, aspartyl protease 2, asp 2, and APP beta-secretase, and membrane-associated aspartic protease 2.
