Fig. 3.
gPP2A‐C mRNA and protein are upregulated in cysts and during excystation stage 1.
Upper panel: SAGE analyses show steady state mRNA levels in vegetative trophozoites (T), total cultures encysting for 4, 21 or 42 h, cysts (C), stage 1 (S1) and stage 2 (S2) excysting cells and 30 and 60 min after excystation.
Lower panel: Western blot analysis of total cell protein from the same stages in Giardia differentiation. The highest amount of gPP2A‐C protein was detected in cysts and Stage 1 of excystation relative to the PDI‐2 protein loading control shown at the bottom of the figure (PDI‐2).
