I've seen the term "1:10000" used to define Product P7000, Pepsin from porcine gastric mucosa (Pepsin A). What does that mean?
A historical measurement of pepsin activity was the ratio of pepsin to coagulated egg white that the pepsin would digest. Thus 1:10,000 would refer to one part pepsin to 10,000 parts coagulated egg white. More recent analyses use hemoglobin as a substrate, in place of coagulated egg white.
Can I freeze stock solutions of Product P7000, Pepsin from porcine gastric mucosa (Pepsin A)?
Solutions of the enzyme at pH 4.4 should be stable at -20 °C for 2-3 months.
Product P7000, Pepsin from porcine gastric mucosa (Pepsin A), can be stored at room temperature, but other pepsins are stored in the cooler or freezer. Why is this?
This relates to autodigestion of pepsin. P7000 is a relatively "crude" pepsin, where other proteins that are present would be more likely digestion targets. With more purified pepsin, the risk of autodigestion increases, and storage at colder temperatures reduces that risk.
