Qiagen, Ambion

Qiagen has recently introduced its line of BioSprint DNA plant kits, which allow for automated purification of plant DNA using the company's BioSprint workstations.

According to Qiagen, the kits use magnetic-particle technology for purification of highly pure DNA from plant tissue. Automation on the BioSprint 15 or BioSprint 96 workstation enables processing of one to 15, or up to 96, samples per run, respectively.

Additional details about the kits can be found at http://www1.qiagen.com/Products/GenomicDnaStabilizationPurification/AnimalPlantSamples.aspx.


Ambion has recently launched the Globinclear-Human whole blood globin reduction kit.

According to the company, the kit removes more than 95 percent of globin mRNA from human whole blood total RNA samples.

The process begins with "the addition of biotinylated capture oligos to a human whole blood total RNA sample," Ambion said. "After hybridization of the capture oligos to the globin mRNA, streptavidin beads are added. The streptavidin beads with their associated globin mRNA are then separated from the total RNA via magnetic capture. The total RNA is further purified using a magnetic bead-based purification procedure. The resulting total RNA is ready for amplification/labeling," according to the company.
