Fig. 4.
Reactivity of mAbs 2H5/D3 and 1B11/A5 with placental parasites using tissue cryosections of a placenta from West African women.
Positive IF staining of sequestered mIE (plain arrow) with 10 μg/mL anti-mIECSA mAb (A) and with 10 μg/mL anti–DBL-γ3 mAb 1B11/A5 (B). Panels C and D show the corresponding placental cryosections under standard light transmission microscopy. A plain arrow shows the mIE corresponding to the IF-stained mIE in the upper part of the figure. Open arrows show that some of the mIEs are not recognized by these mAbs.
