How much protein does one vial of Protease in the QIAamp spin kits contain? What is the concentration of the resuspended Protease?

A vial of Protease with 7.5 Anson units (AU) contains approximately 167 mg protein (45 mAU/mg protein). If the content of the vial is diluted in 7 ml, the concentration would roughly be 24 mg/ml.
