Fully automated total RNA isolation using the RNeasy 96 BioRobot 8000 Kit is performed on the BioRobot 8000 workstation or BioRobot Universal System. The BioRobot worktable has the capacity to purify RNA from up to 192 samples in a single run. With the one-plate protocol, the system can carry out both RNA purification and reaction setup in a single run – from living cell cultures in 96-well plates to RT-PCR mixtures, ready to use in real-time gene expression analysis. Filter tips prevent cross-contamination, and precision robotic handling provides minimal well-to-well variation and high repeatability. RNA purification can also be performed manually on the QIAvac 96 vacuum manifold and/or the 96-Well-Plate Centrifugation System using the RNeasy 96 Kit.
The RNeasy 96 Universal Tissue 8000 Kit integrates efficient phenol/guanidine-based lysis and silica-membrane purification with the speed of vacuum processing. Following homogenization and phase separation, the BioRobot 8000 workstation or BioRobot Universal System provides walkaway automation of the procedure, for total RNA purification from all types of animal tissue (see flowchart " RNeasy 96 Universal Tissue 8000 procedure").
Tissue is first efficiently lysed using QIAzol Lysis Reagent and the TissueLyser II. This provides rapid and parallel disruption of tissues and inactivation of RNases to ensure purification of intact RNA. After phase separation by centrifugation, the BioRobot workstation removes the aqueous phase and adds ethanol to provide appropriate binding conditions. The workstation then applies the sample to the wells of the RNeasy 96 Universal Tissue plate, where total RNA binds and contaminants are efficiently washed away. High-performance RNA is then eluted in a small volume of water, ready for use in any downstream application.
