General description

PCR grade water is sterile-filtered. It is free from exonucleases (DNAse, RNAse) and endonuclease (NICKase) and is also free from nucleic acid contamination.

Application

Water has been used to make up the final volume of the sample in polymerase chain reaction (PCR).
Water has been used:
  • as a component of the reaction mixture and as a diluting agent in microfluidic RT-qPCR
  • as a component of the reaction mixture for the amplification of products from fungal (Trametes versicolor) DNA
  • as a diluting agent and as a component of the reaction mixture for the amplification of cDNA

Suitability

Suitable for polymerase chain reaction (PCR)
