Figure 2From: Induction of long-lasting protective immunity against Toxoplasma gondii in BALB/c mice by recombinant surface antigen 1 protein encapsulated in poly (lactide-co-glycolide) microparticlesScanning electron micrograph of PLG-rSAG1 microparticles. The morphology of PLG-rSAG1 microparticles was inspected by scanning electron microscopy and showed a uniform population of spherical particles with a smooth surface (bar represents 10 μm).Back to article page
