Notes
KMO #11307 was tested with various amounts of enzyme. The reactions in KMO Assay Buffer (50 mM Sodium Phosphate, pH 7.5, 0.1% (w/v) Brij-35) contains 200 uM NADPH, 400 uM L-Kynurenine, and various concentrations of KMO. The reaction mixture incubated for 90 minutes while reading the UV absorption signal. For the negative control (blank), assay buffer was added instead of the enzyme. Absorption signals at 340 nm were measured using a Tecan Infinite M1000 plate reader.
Avoid multiple freeze/thaw cycles.
