Producers' protocol equipped with kits are followed. The strategy useful for lysis of gram favourable organisms just before extraction of your DNA for PCR is crucial. Unless DNA concentrations are established before PCR Evaluation, it might be required to examination dilutions in the DNA sample in order to avoid false negative outcomes brought on by way too minor or a lot of DNA when making use of commercially obtainable kits. We recommend the usage of not more than 344 ng of complete DNA be utilized for the PCR Assessment.
