Apex ultra pure, molecular/proteomic grade water is suitable for use in molecular biology applications that demand assurance that the water is free from DNase, RNase, Protease and endotoxin contamination. No toxic agents, such as DEPC, are used in the manufacturing of this water, eliminating DEPC interference of enzymatic reactions. Apex ultra pure water is ideal for many fundamental procedures such as PCR, electrophoresis, DNA sequencing, and buffers for enzymatic analyses, etc.
