Figure 6From: Electrochemical sensors, MTT and immunofluorescence assays for monitoring the proliferation effects of cissus populnea extracts on Sertoli cellsFluorescence assay results for the residual activities of the active fractions at smaller concentration intervals. (a) Hexane fraction, (b) Butanol fraction, (c) combined/mixed fractions of hexane and butanol. Optimum cell culture conditions: 5-10% CO2, 90% humidity and a constant temperature of 37°C. Other conditions are as in Figure 5.Back to article page
