DupSeq of Rattus norveticus: adult liver; 1.2X N-ethyl-N-nitrosourea; Lab TS
DNA mixtures of BaP- and ENU-treated samples were constructed to create standards with target 1.2-, 1.5-, and 2.0-fold greater mutation frequency than the untreated control. Libraries for eac mixture were prepared by eight different laboratories using TwinStrand DuplexSeq Mutagenesis kits.
