Removal of RNA from DNA sample with using ribonuclease immobilized on carbonyldiimidazole activated CIM disk. Mixture of total RNA and genomic DNA isolated from Aspergillus niger was injected in ribonuclease reactor (two injections each marked with +) and control reactor (marked −). Eluents from reactors were collected and the presence of RNA in genomic DNA samples was detected using 1.6% agarose gel electrophoresis and staining with ethidium bromide. Positions of genomic DNA (gDNA) and RNA (23S, 16S and 5S rRNA) are indicated at the right site of the electrophoretic image. Reproduced with permission from [56]. Copyright 2007 Elsevier.
