DNase Free Certification

The DNase Detection Assay will test for the presence of common environmental DNases (human, bacterial) and qualify products tested to be safe for use in DNA related work. Passing lots are accompanied with a certificate of conformity.

The test is best performed in conjunction with the RNase Detection Assay, as an indicator of the cleanliness of the manufacturing and efficacy of sterilization programs.

DNase is a common laboratory contaminant as it is biologically active in tears, saliva, and to a minimal degree detectable on human skin. Humans and bacteria are the primary source for deoxyribonucleases. Precautions should be taken to ensure that glassware, solutions, reagents, workspace, tools, and gloves are free from deoxyribonuclease contamination when working with DNA.
