Backward Outer primer (B3)
The backward outer primer (B3) is one of the six primers needed to carry out Loop Mediated Isothermal Amplification (LAMP).
Usage and Biology
Very brief explanation on what LAMP is (can re-use this explanation for all 6 parts). Explain specifically how B3 anneals to the DNA sequence.
The loop-mediated isothermal amplification (LAMP) is a rapid method that allows for the specific DNA amplification through the utilization of multiple primers and three major steps (Notomi et al., 2000). This method relies on 3 major components- Bst, a DNA polymerase, and two sets of primers, and the target DNA/RNA. The first step, referred to as the “starting material producing step”, composes the stem-looped DNA that is needed for the second stage. The forward and backward inward and outer primers bind to the complementary sequences within the target DNA sequence (Notomi et al., 2000). The stem-looped DNA undergoes additional annealing within the target sequences and with the Bst polymerase, which produces stem-loop DNA which concludes the first step (Notomi et al., 2000). The stem-loop DNA enters into step two- “cycling amplification step”, which uses the internal primers FIP and BIP in hybridization and synthesis reactions to produce an original and a repaired stem-loop DNA strands (Notomi et al., 2000). For further amplification, loop primers can be inserted into the reactions (Niessen & Vogel, 2010). The third step is “elongation and recycling”, where the DNA products are recycled and elongated through a BIP-primed strand displacement reaction (Notomi et al., 2000).
