Fig. 1From: Development and evaluation of a Loop Mediated Isothermal Amplification (LAMP) technique for the detection of hookworm (Necator americanus) infection in fecal samplesA photo showing the colour change using SYBR green nucleic acid stain as a method of visualizing LAMP amplicons. Samples 1 to 5 were positive for hookworms hence the observed colour change from orange to green, while sample 6 was the negative control thus there was no colour changeBack to article page
