Loop-mediated Isothermal Amplification of DNA

Enhancing Loop-Mediated Isothermal Amplification (LAMP) with SBS Genetech's Bst P DNA/RNA Polymerase

December 15, 2023

Loop-mediated isothermal amplification of DNA is a powerful molecular biology technique used to amplify specific DNA sequences under isothermal conditions. Unlike traditional polymerase chain reaction (PCR), which requires thermal cycling through different temperature steps, LAMP amplifies DNA at a constant temperature, typically between 60-65°C.

The LAMP reaction relies on a strand-displacing DNA polymerase, usually Bst DNA polymerase, and a set of four to six primers that recognize multiple regions within the target DNA sequence. These primers initiate DNA synthesis in a cyclic manner, leading to the formation of stem-loop DNA structures known as amplicons. These structures serve as templates for further amplification, resulting in exponential accumulation of DNA.

Key features of LAMP include:

  • Isothermal amplification: The reaction is conducted at a constant temperature, eliminating the need for a thermal cycler and simplifying the amplification process.
  • High specificity: LAMP employs multiple primers that recognize different regions of the target sequence, enhancing specificity and reducing the likelihood of nonspecific amplification.
  • Efficiency: LAMP is highly efficient and can amplify target DNA rapidly, typically within 30-60 minutes.
  • Visual detection: The amplification products can often be detected visually by the naked eye through turbidity caused by magnesium pyrophosphate precipitation or by the addition of DNA intercalating dyes that produce a color change.
  • Robustness: LAMP is less sensitive to inhibitors present in crude samples compared to PCR, making it suitable for direct amplification from complex biological samples such as blood, urine, or saliva.

LAMP has found widespread applications in various fields including clinical diagnostics, food safety testing, environmental monitoring, and point-of-care diagnostics due to its simplicity, rapidity, and versatility.
