Comparison of MSP-1 and MSP-2 genotype with molecular bar code assay. Patient samples from Senegal and Malawi were genotyped using standard MSP1/2 methods. Examples of samples where both molecular bar code and MSP1/2 methods matched are shown in the upper right (single genome, white background) and the lower left (mixed genomes, orange background), with unmatched examples shown in the upper right and lower left (gray background). Samples having a single product for each of MSP-1 and MSP-2 were shown to have a single bar code (top left, white background) and a mixed bar code (top right, gray background). Mixed MSP-1 and MSP-2 samples were shown to have a single bar code (bottom left, gray background) and a mixed bar code (bottom right, orange background) using the molecular bar code technology.
