Figure 1. The representative scheme of loop-mediated isothermal amplification of DNA with a complete set of primers and the corresponding complimentary regions of a template: F3 and B3 – the outer primers; F3c and B3c – the corresponding template complimentary regions; FIP and BIP – the inner primers (FIP is composed of F2 and F1c regions; BIP is composed of B1c and B2 regions; F1, F2c, B2c, and B1 – the corresponding complimentary regions on the template); LF and LB – the loop primers; LFc and LBc – the corresponding complimentary regions. The arrow indicates the direction of DNA strand synthesis by the strand-displacing polymerase.
