An alternative DNA amplification method was described by Notomi and coworkers [2] called 'loop mediated isothermal amplification' (LAMP). The LAMP assay relies on the design of a set of primers that generate stem looped (hairpin) structures during the early stage of DNA synthesis. The hairpin structures form because two of the primers used contain, at their 5' end, a reverse complement of a sequence that is present in the target further downstream of the initial binding site. Displacement primers help the formation of these hairpins at the ends of the DNA strands and once formed, these structures can be copied into a series of DNA fragments containing multiple units of the target sequence under isothermal conditions utilizing the displacement properties of Bst polymerase (see [3] ). Although LAMP was first described using a set of four primers, enhanced sensitivity was reported using an additional pair of loop primers [4] . As the reactions are performed at a single temperature, LAMP assays can be performed very quickly since there are no separate denaturation, annealing and extension steps, and as such, reactions do not require thermalcyclers. Here we assess the LAMP protocol for the detection of GMOs using primers that target event-specific sequences for transgenic MS8 and RF3 oilseed rape (Brassica napus L.) and generic GMO sequences such as the cauliflower mosaic virus 35S promoter (P-35S) and the promoter and terminator for the nopaline synthase gene (P-nos and T-nos, respectively) from Agrobacterium spp.
