X. Principle The MagListo TM 5M Cell Total RNA Extraction kit is designed for the extraction of highly purified total RNA from cultured cells. For instance, chaotropic agents in Binding Buffer contains Guanidine hydrochloride or Guanidine thiocyanate, as which removes water molecules around RNA and silica coated magnetic bead surface resulting in RNA captured by silica coated magnetic beads. The magnetic bead and nucleic acid complexes are pulled and fixed on the tube wall using a magnetic force, followed by washing with Washing Buffers to remove debris and excessive salts. The captured nucleic acids are then eluted by Elution Buffer, an aqueous solution with optimal ph. Lysis Binding Washing Elution 4

Protocol for Micro(~10 4 )/Mini(1x10 5 ~5X10 6 )/Midi (5x10 6 ~2x10 7 ) Extraction Harvest of Cells 1. Cells grown in suspension : Count the cell number and centrifuge the proper number of cells at 300 x g for 5 min. Discard supernatant carefully and go to Lysis & Homogenization (step 3). 2. Cells grown in a monolayer: There are 2 different ways to collect cells grown in a monolayer. A. Direct cell lysis on the Culture Dish: Completely remove cell culture medium and go to Lysis & Homogenization (step 3). (Remaining medium may inhibit the RNA extraction) B. Harvesting cells with trypsin: Remove Cell Culture Medium and wash the monolayer with DPBS. Add 0.1%-0.25% typsin to the washed cell monolayer. When the cells are detached, add Cell Culture Medium to inactivate the typsin. Transfer the cells into a RNase-free tube and centrifuge at 300 x g for 5 min. Discard supernatant carefully and go to Lysis & Homogenization (step 3). Lysis & homogenization 3. Add 50 µl (micro) / 400 µl (mini)/ 2 ml(midi) of Buffer 1 (Binding) to the Cell culture Dish or the collected cell pellet and completely homogenize the cells by pipetting or vortexing for at least 1 min. (Note) Insufficient homogenization can decrease the RNA purification yield, and also cause clogging of Magnetic Nano beads in the following steps. For the sufficient homogenization of the lysate, make the lysate passed through blunt 20-gauge needle (0.9 mm diameter) 5 to 10 times. A. For (micro/mini) scale extraction, please transfer the Lysate to a 2 ml (or 1.5 ml) tube. B. For (midi) scale extraction, please transfer the Lysate to a 15 ml tube. RNA binding 4. Add 50 µl for (micro) 400 µl (mini)/ 2 ml (midi) scale extraction of Absolute Ethanol to the tube and mix by vortexing or shaking. 5. Add 50 µl for (micro)/ 100 µl (mini)/ 400 µl (midi) scale extraction of Magnetic Nano Bead solution to the tube and mix by Vortexing or shaking. (Note) Magnetic Nano Bead solution contains magnetic nano beads. Please Vortex well before use. 7

XIII. Troubleshooting Guide Comments and suggestions Insufficient Homogenization: (Refer to Page 7) add Buffer 1 (Binding) to the cells and completely homogenize the cells by vortexing for at least 1min or increase the vortexing time for the sufficient homogenization up to 5 to 10 minutes. Use of an excess amount of sample: Use the proper amount of samples according to the instructions of this User s Guide. Low or no yield Insufficient Bead dry: Beads must be completely dried. Any leftover of ethanol can decrease the RNA purification yield. Insufficient incubation during the Elution step: RNA could remain attached to the beads if the incubation time is not enough. To prevent this, please repeat the Elution process with the increased incubation time. Incomplete removal of Cell Culture medium: The best approach is to remove the medium as much as possible. Any leftover in the medium can lead to the inhibition of RNA extraction. Aggregation of Magnetic Nano Beads RNA degradation Inhibition of downstream enzymatic reactions Low A 260/280 ratio Insufficient Homogenization: (Refer to Page 7) add Buffer1 (Binding) to the cells and completely homogenize the cells by vortexing for at least 1min or increase the vortexing time for the sufficient homogenization. Use of an excess amount of sample: Use the proper amount of samples according to the instructions of this User s Guide. RNase contamination: Use a heat gun or a blow dryer in a clean bench to prevent the contamination of RNase in the air. Use RNase-free pipette tips and change the gloves frequently. Inappropriate handling of harvested samples: If the extraction is not performed right after harvesting the samples, store the samples at -80 or lysis the samples with Buffer 1 (Binding) and then store at -80. Insufficient Bead dry: Beads must be completely dried. Any leftover in the ethanol can decrease the RNA purification yield. Insufficient washing during the bead suspension process: Insufficient suspension of beads during the washing step causes salts to remain in the purified RNA. The recommendation is to suspend the beads thoroughly during the washing process. Insufficient Bead dry: Beads must be completely dried. Any leftover in the ethanol can decrease the RNA purification yield. Insufficient washing during the bead suspension process: Insufficient suspension of beads during the washing step causes salts to remain in the purified RNA.
