DNase I is a deoxyribonuclease, an endonuclease that preferentially cleaves double-stranded DNA, commonly used in molecular biology for removing DNA contamination from RNA samples and in cell culture to reduce viscosity. Available in liquid or lyophilized form, it is stable at -15 to -20 °C. CAS: 9003-98-9. Signal word: Danger. Molekula supplies DNase I from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
