Fig. 2From: A two-colour multiplexed lateral flow immunoassay system to differentially detect human malaria species on a single test lineRepresentative test strips of the two-colour LFA. Distinct colours were observed at the test lines, corresponding a type of antigens, such as a blue test lines for pLDH detection only, b mixture colour of test lines for simultaneous detection, and c red test lines for PfHRP2 detection only. The mixture colour at control lines indicated the red and blue latex particles migrated along the length of the stripBack to article page
