【LAMP法の解説】Overview of the LAMP Method
　LAMP法（Loop-Mediated Isothermal Amplification）は、標的遺伝子上の特異的配列に基づく複数プライマーを用い、鎖置換型DNAポリメラーゼによって反応させることで、短時間で爆発的な標的配列の増幅をさせる反応です。分子識別技術としてよく用いられるPCRに比べて、変性反応が必要なく定温で反応が進むため、サーマルサイクラーのような特殊機器を必要とせず、特異性が高く迅速に診断できます。
　The LAMP method (Loop-Mediated Isothermal Amplification) is a reaction that uses multiple primers targeting specific sequences on the target gene and is driven by strand-displacing DNA polymerase, enabling rapid and exponential amplification of the target sequence in a short time. Compared to PCR, which is also commonly used as a molecular identification technique, LAMP proceeds under isothermal conditions without the need for denaturation steps, thus eliminating the requirement for specialized equipment like thermal cyclers. This makes it highly specific and allows for rapid diagnosis.
