New Automated Extraction System Produces High Quality RNA-free DNA

The instrument can draw samples from a variety of primary tube sizes, running up to 30 samples in a batch. It reads and records barcodes on primary tubes, has an internal barcode scanner to verify sample input and DNA output positions, provides liquid level detection for accurate pipetting, and delivers its final elution in SBS (sterile barrier system)-type storage tubes of the user’s choosing.

FlexSTAR+ features sample tracking and reporting software that verifies work lists from LIM (laboratory information management) input, creates a map of sample and DNA positions, tracks samples through the extraction process, and sends final reports back to LIMs. The software also sends an email or text alert to notify the operator when the run is complete.

The extraction process operates with Qiagen (Venlo, The Netherlands) FlexiGene chemistry. This precipitation-based procedure yields cleaner, longer-stranded DNA than does magnetic bead-based methods. Furthermore, since the Qiagen DNA extraction process begins with the collection of the white cell nuclei pellet, it eliminates RNA contamination that can occur with magnetic bead technology and other technologies that produce total nucleic acid instead of pure genomic DNA.

“Biorepositories, genetic treatment and cancer centers, and specialty diagnostic labs that currently are using Qiagen’s AutoPure solution for DNA extraction will be familiar and comfortable with precipitation technology,” said Bob Sullivan, president and CEO of AutoGen. “FlexSTAR+ is a logical step-up for them. In fact, it is a superior solution for any lab that wants to generate higher quality, higher yield genomic DNA with less work and errors and far less likelihood of RNA contamination, and that stands to benefit from the superior service for which AutoGen is known.”
