Fig. 3From: Superoxide-producing lipoprotein fraction from Stevia leaves: definition of specific activityOptical absorption spectrum of Nox isoforms isolated from erythrocyte (1) and Stevia (2) membranes. Nox isolated from membranes of 10 ml of erythrocytes with a volume of 12 ml and from membranes of 10 g of dry Stevia leaves with a volume of 2 ml. Nox isoforms are dissolved in 0.1 M PPB, pH 7.4 (p < 0.05, n = 6)Back to article page
