Transfected parasites were cloned by limiting dilution, and clones with the highest fluorescence intensity in both species were selected for further use in drug screening assays. Immunology and Infection Separation of Plasmodium falciparum Late Stage-infected Erythrocytes by Magnetic Means Lorena Michelle Coronado1,2, Nicole Michelle Tayler1,2, Ricardo Correa1,2, Rita Marissa Giovani3, Carmenza Spadafora1 1Centro de Biología Celular y Molecular de Enfermedades, Instituto de Investigaciones Científicas y Servicios de Alta Tecnología (INDICASAT AIP), 2Acharya Nagarjuna University, 3Departamento de Medios y Creativo, Instituto de Investigaciones Científicas y Servicios de Alta Tecnología (INDICASAT AIP) The paramagnetic properties of hemozoin are used to isolate late stages of Plasmodium falciparum-infected red blood cells growing in culture. The method is simple and fast and does not affect the subsequent invasive capabilities of the parasites.
