BACE1 Protein, Human (HEK293, N-His)

BACE1 protein is crucial in proteolytic processing of amyloid precursor protein (APP), initiating cleavage at the N-terminus of the A-beta peptide sequence. This process results in the extracellular release of beta-cleaved soluble APP and a cell-associated C-terminal fragment. BACE1's cleavage activity extends to CHL1, demonstrating its versatility in substrate processing. BACE1 Protein, Human (HEK293, N-His) is the recombinant human-derived BACE1 protein, expressed by HEK293 , with N-6*His labeled tag. The total length of BACE1 Protein, Human (HEK293, N-His) is 436 a.a., with molecular weight of 56-85 kDa.

The BACE1 protein plays a pivotal role in the proteolytic processing of the amyloid precursor protein (APP). It initiates cleavage at the N-terminus of the A-beta peptide sequence, specifically between residues 671 and 672 of APP, resulting in the production and subsequent extracellular release of beta-cleaved soluble APP. Simultaneously, BACE1 generates a corresponding cell-associated C-terminal fragment, subsequently released by gamma-secretase. In addition to its primary target, BACE1 also exhibits cleavage activity on CHL1, as observed through its similarity in cleaving this substrate.

Measured by its ability to cleave a fluorogenic peptide substrate, Mca-SEVNLDAEFRK(Dpn)RR-NH2. Read at excitation and emission wavelengths of 320 nm and 405 nm. The specific activity is 173.598 pmoL/min/µg, as measured under the described conditions.

Lyophilized powder.

Lyophilized a 0.2 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
