AOF BP Protease
(Cat. # 003-1000)
GMP Grade BP Protease is an affordable, aseptically dispensed, lyophilized protein containing purified neutral protease from Bacillus polymyxa.1 This 1.1 million NP Unit pack size can be used to work with our collagenases to isolate islets, hepatocytes, human epithelial skin cells, and adipose derived stromal cells.
- White lyophilized cake under vacuum in amber bottle sealed with butyl rubber stopper
- Vial contains 1.1 million Neutral Protease (NP) units, with total NP activity >800,000 NP Units
- Stable for at least 2 years when stored at < -20 °C
This product is purified from culture supernatants of of B. polymyxa using column chromatography. No animal derived components were used in the culture or the subsequent purification steps.
After assessing enzyme potency, the protease is aseptically dispensed into depyrogenated vials and lyophilized. When dry, the BP Protease vials are sealed under vacuum. A representative sample from the batch is reconstituted and analyzed by a variety of quality control tests. Results are compared to established specifications before release into inventory.
The specific neutral protease activity of purified BP Protease is determined by the FITC-BSA substrate NP3. The specific activity is used to provide a total target number of NP units.
