Figure 7From: Electrochemical sensors, MTT and immunofluorescence assays for monitoring the proliferation effects of cissus populnea extracts on Sertoli cellsDOX sensor results. (a) Hexane fraction containing TM4 cells at varying concentrations of plant extracts. X = 1.25 × 10(4) cell/ml, (b) the calibration curve recorded at 1800 seconds for the DOX sensor array. Optimum applied potential used was -300 mV.Back to article page
