Automation note
The official protocol also provides a 32/48-channel extractor setup. After MagZol / BCP phase separation, 400–500 µL supernatant is added to Row 1/7 containing isopropanol and MagPure Particles N, and program #R6623 is run for approximately 30 min. This workflow note uses the manual magnetic-bead route for the standard cumulative timeline.
How to Read This Note
1. Workflow structure
This workflow separates sample-specific pretreatment from the shared downstream purification path. It is intended as a practical companion to the product manual rather than a replacement for the official protocol. Where multiple protocol routes are available, this note focuses on the route that best represents the key workflow logic of this product.
2. Time interpretation
Protocol times stated in the product manual are retained where applicable. Steps without explicit timing are estimated for an experienced operator, including pipetting, tube transfer, centrifuge or magnetic-rack handling, supernatant / filtrate removal and tube, plate or column repositioning. For short protocol ranges, the timeline uses the midpoint. For long or optional protocol ranges, the displayed standard timeline uses the shortest reasonable path, while the note and total-time range indicate where extended handling may apply. Cumulative time runs continuously from the first step to final elution across all workflow sections.
3. Workflow characteristics
R6623 uses a MagZol / BCP phase-separation front end followed by magnetic-particle RNA purification. The main workflow logic is sample disruption in MagZol Reagent, BCP-assisted phase separation to remove genomic DNA and protein impurities, recovery of the clarified RNA-containing upper phase, and RNA capture on MagPure Particles N under isopropanol-assisted binding conditions. This note uses the manual magnetic-bead route as the standard cumulative timeline, while the automation route is summarized separately because it starts after the same phase-separation step.
4. Practical considerations
Front-end lysis quality is strongly sample dependent. Fibrous tissue, plant powder, bone, blood vessels, fungi, bacteria and blood-cell or bone-marrow pellets may require careful homogenization, enzymatic pretreatment or bead-tube disruption before the shared phase-separation step. During BCP mixing, vigorous hand shaking is required; slow inversion may reduce extraction efficiency, while vortex mixing at this step may increase DNA contamination. After centrifugation, transfer only the clarified upper phase and avoid disturbing the interphase. Ensure MW1 and MW2 are prepared with ethanol, remove residual wash buffer thoroughly, and avoid excessive bead over-drying before elution.
