Regarding the activity, sorry, we haven't tested the activity of this protein, so its activity is not 100% guaranteed.
In theory, we adopt affinity chromatography for puritication, which is purified under a very mild condition, it's very likely to be active.
We could recommend you to purchase a small size to have try.
