Tracing Phosphate Ions Generated during Loop-Mediated Isothermal Amplification for Electrochemical Detection of Nosema bombycis Genomic DNA PTP1.Traditionally, amplified DNA detection in a loop-mediated isothermal amplification (LAMP) was carried out in a complicated gel electrophoresis or with expensive fluorescence-based methods.  Pyrophosphate (PPi) as the byproduct of nucleic acid polymerization reaction in LAMP was hydrolyzed into Pi by the preaddition of thermostable inorganic pyrophosphatase (PPase).
