Akonni Biosystems this week launched the TruTip kit for extracting genomic DNA from fresh or frozen whole blood.

TruTip uses a nucleic acid-binding matrix that inserts into either a Rainin EDP 3-Plus pipette, ideal for extracting a few samples; or an Eppendorf epMotion system, for extraction workflows that require a higher level of throughput.

Akonni also said that TruTip can be adapted to work with most other standard electronic pipettes and automated liquid-handling systems. According to the company, when automated, extracting human genomic DNA from blood is five times faster with TruTip than with spin columns, easily extracting samples from 50 µL to 400 µL in minutes.

Akonni said that it is also currently developing TruTip kits for extracting a variety of nucleic acid targets from a range of clinical samples, including sputum, nasal wash, urine, stool, or cerebrospinal fluid.

Promega this week launched the ReliaPrep Blood and Tissue gDNA miniprep systems for extracting high yields of gDNA from challenging samples, such as frozen blood.

The ReliaPrep Blood miniprep system purifies intact gDNA from up to 200 µL of blood or body fluid. Genomic DNA can be prepared from fresh or frozen blood in less than 40 minutes, with expected DNA yields of 4 µg to 10 µg, depending on the white blood cell count of the sample.

Meantime, Promega said that the ReliaPrep Tissue miniprep system purifies gDNA from up to 25 mg of tissue.
