Product News: Porvair Sciences launches new columns for rapid removal of gDNA from RNA samples

27 May 2021


Porvair Sciences has launched Chromatrap® gDNA Removal Columns that quickly remove unwanted genomic DNA (gDNA) from RNA samples.

Removal of gDNA from RNA samples is of particular importance to scientists undertaking RT-PCR, RNA-seq, and microarray-based applications where the high purity and accurate measurement of RNA is vital.

Employing a simple load and spin method the new columns efficiently capture gDNA on the membrane allowing efficient flow-through of DNA-free cell lysates for downstream RNA purification. Unlike traditional gDNA removal methods - Chromatrap® gDNA removal columns require no time-consuming enzymatic digestion that can also impact RNA purity. 

Beneficially using the Chromatrap® spin column methodology the captured gDNA may also be eluted for use in downstream applications such as g PCR, Southern blotting, cloning, and sequencing.
