Molecular Test “LAMP”

What is LAMP?

"LAMP" which stands for Loop-mediated Isothermal Amplification is a simple, rapid, specific and cost-effective nucleic acid amplification method solely developed by Eiken Chemical Co., Ltd.

It is characterized by the use of 4 different primers specifically designed to recognize 6 distinct regions on the target gene and the reaction process proceeds at a constant temperature using strand displacement reaction. Amplification and detection of gene can be completed in a single step, by incubating the mixture of samples, primers, DNA polymerase with strand displacement activity and substrates at a constant temperature (about 65°C).

It provides high amplification efficiency, with DNA being amplified 10^9-10^10 times in 15-60 minutes. Because of its high specificity, the presence of amplified product can indicate the presence of target gene.

How can primers be designed?

Design 4 types of primers based on the following 6 distinct regions of the target gene: the F3c, F2c and F1c regions at the 3' side and the B1, B2 and B3 regions at the 5' side.

For more information about primers, the priniciple of LAMP and technical information: Eiken Genome Site

The each primer region can be determined by using the PrimerExplore (a special software to design LAMP primers) after considering the base composition, GC contents and the formation of secondary structures. Tm value can be obtained by Nearest Neighbor method.
