Fig. 2From: Detection of Plasmodium falciparum DNA in saliva samples stored at room temperature: potential for a non-invasive saliva-based diagnostic test for malariaComparison of total DNA concentration in Plasmodium falciparum positive saliva samples. DNA was extracted from 200 µl of saliva when they were initially collected and quantified. The saliva samples were left at room temperature for 1 year and DNA was re-extracted and quantified. ***P = 0.0002Back to article page
