The ROTI ® Nucleic Acid-free products are not suitable for the removal of virus contamination. ROTI ® Nucleic Acid-free eXtra ready-to-use ROTI ® Nucleic Acid-free eXtra is a very gently and highly efficient solution that has been designed as nonhazardous alternative to our top-selling ROTI ® Nucleic Acid-free. The ready-to-use solution or spray may be used for fast elimination of all kinds of contaminating nucleic acids (e.g. gDNA, amplicons, plasmids, RNA) from surfaces without the need to handle dangerous liquids. Contamination with foreign DNA or RNA, which may heavily interfere with sensitive assays like PCR, reverse transcription or sequencing, is hence efficiently eliminated.

By incubation or by wiping, laboratory benches, heating blocks, thermal cyclers, pipettor shafts, reaction tubes etc. can easily be cleaned. We recommend to test the reagent in an inconspicuous place before using it over a large area.
