32 QIAxcel Advanced Application Guide 10/2016 Conclusions Although many DNA markers are recorded in the Arabidopsis thaliana database, markers with differences of only several bases pairs may be difficult to analyze. We anticipate that the use of the QIAxcel system, which demonstrates superior separation capability and simplicity, will enable the effective use of these markers and further increase the speed of mapping and genotyping.
