Worthington Biochemical FAQ

What are conversion factors for units of Deoxyribonuclease (D/DP/DPRFF)?

Note: Kunitz units as reported by other suppliers can be 2-4 times higher than Kunitz units as measured at Worthington. As measured at Worthington one Kunitz unit digests 1 ug of calf thymus DNA in 10 min at 37C in 50mM Tris, 1 mMMg++, 1 mMCa++, pH 7.8. Correlation of digestion units with Kunitz units is different for other DNA and buffer systems. When protease is present, units can not be correlated.
