Fig. 4From: Direct transfer of HRPII-magnetic bead complexes to malaria rapid diagnostic tests significantly improves test sensitivityParacheck RDTs before (top) and after (bottom) magnetic bead-based enhancement. The top RDT shows the result of applying a 5 µL blood sample containing 200 parasites/µL according to the manufacturer’s protocol. The bottom RDT shows enhancement at the test line after using the bead transfer device to apply HRPII-bound magnetic beads after mixing with a 100 µL sample containing 200 parasites/µL. HRPII is released from the deposited beads with imidazole-spiked running bufferBack to article page
