Molecular biology grade water free from Rnase, Dnase, Protease useful for many molecular biology applications Molecular Biology Grade water is suitable for use in molecular biology applications where high quality of water is required and should be free from DNase, RNase and protease contamination. Molecular biology grade water is ideal for the preparation of reagents, rinsing glassware and plasticware, and other molecular biology applications where RNase, DNase, and Protease-free water is required. It is widely used for several fundamental procedures like PCR, gel electrophoresis, DNA sequencing etc
