Worthington Biochemical FAQ

I ordered Collagenase IV from your company (100mg). Some of the protocols call for 2mg/ml concentration and others call for 0.2% solution. How does one prepare a 0.2% solution?

A 0.2% solution is equivalent to 2 mg/ml. Just remember a 1% solution refers to 1 gram per 100 ml or 10 mg/ml.
