Figure 3. Expression of the genes coding for the four salivary proteins during several life stages of I. scapularis.
Quantitative reverse-transcription polymerase chain reaction performed on RNA isolated from whole larvae, and from salivary glands and midguts I. scapularis from nymphs and adults. Expression profile of: A. p8; B. p19; C. p23; and D. p32 in unfed (grey bars) and fed ticks (black bars). SG; salivary glands, MG; midguts.
