Typical Batch Characteristics
P450 Concentration: 0.9 nmol/ml
Protein Concentration: 8.0 mg/ml
Specific P450 Content: 110 pmol/mg protein
Cytochrome c Reductase Activity: 400 nmol/min/mg protein
Typical P450 Activity Data (1)
Activity: 7-ethoxycoumarin O-deethylase
Linear with time up to: 10 min:
Linear with P450 up to: 2.5 pmol/ml:
Vmax: 18 pmol/min/pmol CYP
Km: 5 µM
Typical P450 Activity Data (2)
Activity: 7-ethoxyresorufin O-deethylase
Linear with time up to: 2 min
Linear with P450 up to: 5 pmol/ml
Vmax: 55 pmol/min/pmol CYP
