Fig. 4From: A novel one-step expression and immobilization method for the production of biocatalytic preparationsComparison of activities of free and membrane bound β-gal-cyt b5. The activity of β-gal-cyt b5 immobilized to SUV (a) and the activity of the same samples after solubilization of β-gal-cyt b5 by detergent treatment (b) are compared. The reference activity (c) was obtained from purified β-galactosidase with N-terminal His6-tagBack to article page
