Fig. 2From: An improved nucleic acid extraction method from dried blood spots for amplification of Plasmodium falciparum kelch13 for detection of artemisinin resistanceThe current method outperforms Qiagen based kits for amplification of k13 from dried blood spots. a The optimized protocol (compatible with Omega EZ and Nunc 96-well DNA plates) is able to amplify k13 from all 5000 parasites/mL DBS samples, whereas Qiagen QIAamp and Investigator kits cannot. b Nunc DNA plates show improved sensitivity for amplification of 1000 parasites/mL DBS samples than Omega EZ DNA plates.
