Elimination of contamination in loop-mediated isothermal amplification assay for detection of human malaria.

The LAMP assay, amplifies the target DNA rapidly, with 10-fold greater sensitivity than conventional PCR. The greater sensitivity also comes with greater risks of contamination. To overcome this issue, the current project includes either uracil DNA glycosylase (UDG) or a mineral oil overlay in the LAMP assay. Our results indicated that UDG or a mineral oil overlay can effectively prevent carryover contamination in the LAMP assay for the detection of human malaria. By incorporating these preventative methods, contamination can be eliminated and LAMP can potentially be used in the field; and point of care diagnosis for human malaria.
