Hi everyone

I have had a look around but cannot find any, so I have rang our supplyer but even they weren't sure so I am waiting to hear back Just wondering if anyone has purchased any recently and also if I do get my hands on some how do I mix it up to a solution and how long does it last

Re: Protease ?
I'm pretty sure pepsin is a protease enzyme used in the digestion of protein. In school labs we do it with egg white.
Do you have any of that??
Make up a 1% solution in water and I would discard it when you are finished the prac!!

Re: Protease ?
The egg white is the substrate and the pepsin is the enzyme which will digest the egg white.
