Figure 1.

Pictures of agarose gels showing PCR products of DNA obtained from a hyper-parasitaemic sample which was blotted on RDTs after making two fold serial dilutions (from 1000 to 0.01 asexual parasites/μl) and extracted after storage at room temperature for 30 days with (A) or without (B) silica gels as preservatives. Lanes 1-22 = DNA from serially diluted samples, 23-26 = positive controls (3D7 strain, 7g8 strain, patient sample with 1000 asexual parasites/μl, field sample on filter paper), 27-28 = negative controls and LM = 50 pb ladder marker.
