Immunoelectron micrographs showing sections of ring-infected erythrocytes reacted first with rabbit anti-RESA (A) or ~2 mg/ml of affinity-purified human anti-RESA antibodies (B), then with protein A gold; other sections of merozoites were reacted with rabbit anti-RESA (C-F) or 0.5 mg/ml human anti-RESA antibodies (C), and then protein A gold. (A) X 35,600; (B) X 56,500; (F) X 59,200; (G) X 57,500).
