Fig. 5. Real-time PCR analysis of relative concentrations of CA message in Ae. aegypti larvae. The GC tissue displays the greatest amount of CA message. This value was arbitrarily set to 1 so that the other tissue sections could be relatively compared. The AMG and PMG along with the MT display very little CA message. The head section displays roughly half the amount of message found in the gastric caeca. All samples were normalized to 18S RNA. Values are means ± 1 S.E.M. Abbreviations as in Fig. 2.
