Sensitivity of the LAMP assay. To determine the sensitivity of our assay we cloned the product of the LAMP reaction into a plasmid and then performed the assay using serial dilutions at the following concentrations: 107 (1), 105 (2), 103 (3), 101 (4) and 10° (5). We performed the assay using both a thermocycler (A) and a heat block (B) with both proving suitable. Samples were incubated at 63°C for 90 min. The results were visualized on a 1.5% agarose gel stained with ethidium bromide. M = 1 Kb Plus, Invitrogen NC = negative control.
