Neuroscience
Relevance
Acid protease active in intracellular protein breakdown. Plays a role in APP processing following cleavage and activation by ADAM30 which leads to APP degradation (PubMed:27333034) . Involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease.
Endotoxin
Less than 1.0 EU/μg as determined by LAL method.
Purity
Greater than 95% as determined by SDS-PAGE.
Activity
Yes
Bioactivity
Measured by its ability to cleave the fluorogenic peptide substrate Mca-PLGL-Dpa-AR-NH2.The specific activity is >2000 pmol/min/μg.
Form
Lyophilized powder
Buffer
Lyophilized from a 0.2 μm sterile filtered PBS, 6% Trehalose, pH 7.4
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Molecular Weight

Storage Conditions
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
