Difference between isothermal amplification and colloidal gold

The difference between isothermal amplification and colloidal gold lies in the source of enzyme. The rapid amplification of nucleic acid was carried out at a constant temperature of 37℃. Difference: The sources of enzymes are different, mainly for patent reasons. The recombinant RPA enzyme comes from T4 bacteriophage. The recombinase of ERA comes from bacteria, viruses and phages.
