Web14 mei 2012 · The MDR1 conformational change level was significantly higher in the high-medication-use group than the low-use group (p = 0.028). Basal MDR1 (OR = 1.16 [95% CI: 1.060–1.268]) and conformational change level (OR = 1.11 [95% CI: 1.02–1.20]) were independent predictors for seizure frequency and number of medications, respectively. WebMDR1-MDCK Permeability Assay Experimental Protocol To determine the role of human P-gp, it is recommended to analyze a test compound on both wild type MDCK and MDCK-MDR1 cell monolayer. The wild type MDCK uses as a negative control in confirming the role of human P-gp in the MDR1-MDCK permeability assay.
