Figure 4From: Inhibition of hematopoietic prostaglandin D2 Synthase (H-PGDS) by an alkaloid extract from Combretum molle Inhibition profile of C. molle alkaloids on GST Sigma. A shows the Michaelis-Menten plot and B the Lineweaver-Burk plot of GST Sigma. In the assay GST Sigma activity was measured with varying concentrations of GSH and different inhibitor concentrations; 0, 2, 5, 10 and 20 μg/ml whilst GSH concentration was fixed at 5 mM.Back to article page
