Toxoplasma gondii sialic acid binding protein-1 (TgSABP1) expressed in T. gondii is localized on the outer membrane of tachyzoites. A, Western blot analysis of native SABP1 expression in T. gondii detected by SABP1-specific antibodies. Sera of a healthy rat was used as the negative control. B, The localization of TgSABP1 (red) overlapped with surface antigen-1 (SAG1, green) was detected on the surface of both intracellular and extracellular parasites (without permeabilization) of T. gondii (RH and ME49 strains). Sera of a healthy rat was used as the negative control. Scale bar, 10 μm.
