"LAMP" stands for Loop-mediated Isothermal Amplification. This technology was developed by Notomi et al. It is a very sensitive, easy and time efficient method. The LAMP reaction proceeds at a constant temperature using a strand displacement reaction.
Types of Primers used in LAMP
LAMP is characterized by the use of 4 different primers specifically designed to recognize 6 distinct regions of the target gene. The four primers used are as follows:1. Forward Inner Primer (FIP): The FIP consists of a F2 region at the 3'end and a F1c region at the 5'end. The F2 region is complementary to the F2c region of the template sequence. The F1c region is identical to the F1c region of the template sequence.
2. Forward Outer Primer (FOP): The FOP (also called F3 Primer) consists of a F3 region which is complementary to the F3c region of the template sequence. This primer is shorter in length and lower in concentration than FIP.
3. Backward Inner Primer (BIP): The BIP consists of a B2 region at the 3'end and a B1c region at the 5'end. The B2 region is complementary to the B2c region of the template sequence. The B1c region is identical to the B1c region of the template sequence.
4. Backward Outer Primer (BOP): The BOP (also called B3 Primer) consists of a B3 region which is complementary to the B3c region of the template sequence.
