Automated Nucleic Acid Isolation from HepG2 cells

Nucleic Acid Extraction from HepG2 Cells: An Integrated Solution Utilizing the Bead Ruptor Elite™ Homogenizer, chemagic™ 360 Nucleic Acid Extractor and JANUS® G3 Automated Workstation

Applications featuring Next Generation Sequencing, quantitative PCR, or other genomics-based research using invitro cultured cells requires a nucleic acid extraction upstream of aforementioned methods. The Bead Ruptor Elite™ Bead Mill homogenizer and 2 mL bead kits are a streamlined sample preparation solution that provides efficiency in cell lysis, releasing nucleic acid for extraction on the chemagic™ 360 automated nucleic acid extractor.
In this aplication note, we outline the integration of the Bead Ruptor Elite™ Bead Mill homogenizer with the chemagic™ 360 nucleic acid extractor and Janus® G3 automated workstation, creating an end-to-end solution for sample preparation of in-vitro cultured cells and nucleic acid extraction workflows.

HepG2 DNA concentration from 12 samples

Lysate from samples 1-12 was prepared with Pro-K and RNase A. Average A260 /A280 from samples 1-12 was 2.21.

Nucleic Acid Extraction

After centrifugation step, 100 µl of cell lysate was transferred to 12 separate wells of a 96-well plate using the JANUS G3 automated workstation and customized Reagent Liquid Transfer Winprep program. Similarly, 100 µl Lysis Buffer provided with the chemagic Tissue DNA Kit (CMG-723) was transferred to each well containing the lysate. Next, 6 µl of Proteinase-K, included in the chemagic Tissue DNA kit, was manually transferred to all wells along with 5 µl RNase A. The plate was then incubated at 37°C for 10 minutes. During this time, Elution Buffer and Magnetic Beads were transferred into respective plates using a Reagent Liquid Transfer Protocol on the JANUS G3 automated workstation. After incubation, the tissue DNA extraction was carried out using the chemagic 360 nucleic acid extractor.
