FAQ: The previous Activity/Performance Chart stated that activity in NEBuffer 4 is 50% yet the enzyme is now supplied with CutSmart® Buffer.  What has changed? 

Reformulation of NEBuffer system, including the addition of BSA, allowed some enzymes to work more optimally in CutSmart® Buffer.  This enabled us to offer >200 restriction enzymes that work in a single buffer, greatly increasing convenience for our customers.
