Recombinant Human BACE1, C13&N15-labeled

Cat.No.: BACE1-219H
Product Overview: Recombinant Human BACE1 MS Standard Protein, C13 and N15-labeled (BACE1, Heavy Labeled) Thr 22 - Thr 457 (Accession # NP_036236.1) was produced in human 293 cells (HEK293).
Description: Beta-secretase 1 (BACE1) also known as beta-site APP cleaving enzyme 1 (beta-site amyloid precursor protein cleaving enzyme 1), memapsin-2 (membrane-associated aspartic protease 2), and aspartyl protease 2 (ASP2), β-Secretase , and is a member of the peptidase A1 protein family, BACE1 is a type I integral membrane glycoprotein and aspartic protease that is found mainly in the Golgi. BACE1 is an aspartic-acid protease important in the pathogenesis of Alzheimer"s disease, and in the formation of myelin sheaths in peripheral nerve cells.[1] The transmembrane protein contains two active site aspartate residues in its extracellular protein domain and may function as a dimer. This protease is responsible for the proteolytic processing of the amyloid precursor protein (APP). Generation of the 40 or 42 amino acid-long amyloid-β peptides that aggregate in the brain of Alzheimer"s patients requires two sequential cleavages of the APP. Extracellular cleavage of APP by BACE creates a soluble extracellular fragment and a cell membrane-bound fragment referred to as C99. The elevation of BACE1 levels can be induced by amyloid plaques surrounding neurons at early stages of pathology before neuron death occurs, and may drive a positive-feedback loop in AD. [2-3]
Source: HEK293
Species: Human
Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Mannitol or Trehalose are added as protectants before lyophilization.
Molecular Mass: BACE1, Heavy Labeled, fused with 6×His tag at the C-terminus, has a calculated MW of 49.2 kDa. The predicted N-terminus is Thr 22. DTT-reduced Protein migrates as 50-65 kDa due to glycosylation.
Endotoxin: Less than 1.0 EU per μg of the BACE1, Heavy Labeled by the LAL method.
Purity: >95% as determined by SDS-PAGE.
Storage: Avoid repeated freeze-thaw cycles.No activity loss was observed after storage at:In lyophilized state for 1 year (4oC-8oC); After reconstitution under sterile conditions for 1 month (4oC-8oC) or 3 months (-20oC to -70oC).
