Localisation of laminin in the capsule of P. berghei oocysts. Sections of P. berghei- infected An. stephensi midguts were probed with anti- D. melanogaster laminin-1 antibodies (1:4000) followed by 10 nm gold particle-conjugated secondary antibodies. Laminin is present on the outer surface of the capsule (arrows), within the capsule (arrowhead), and on the inner surface of the capsule (dashed arrow) (60,000 ×; scale bar = 500 nm). Cap = capsule, BL = basal lamina.
