DNAase (more commonly referred to as DNase) stands for Deoxyribonuclease. DNAase can be defined as ' a single, glycosylated polypeptide that degrades unwanted single- and double-stranded DNA'. This enzyme is used both in labs and commercially for multiple functions, one being to remove any unwanted DNA from samples (useful for detecting/purifying the desired product). DNAase is especially useful as it is not specific to either single, or double stranded DNA; it will cleave both. This property is often used in labs - DNAase is added to the sample (containing DNA) in order to reduce the viscosity, making pipetting much more efficient and accurate .
