Fig. 4From: Multiplex-RT-PCR-ELISA panel for detecting mosquito-borne pathogens: Plasmodium sp. preserved and eluted from dried blood spots on sample cardsEfficacy of sample card extraction. Sample cards spotted with the positive controls listed on the x-axis were extracted by one of three methods indicated in the Key (a). Positive controls were either not spotted or spotted on sample cards and eluted by the method of Klüber (unpublished) (b). In all cases, the positive control in the resultant sample was quantified by multiplex-RT-PCR-ELISA. OD-values are the means ± standard deviation of triplicate determinationsBack to article page
