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

9 XII. Protocols Before you begin 1. Buffer 1 (Binding) and Buffer 2 (1 st Washing) contains chaotropic salt. You should take the appropriate laboratory safety precautions and wear gloves and lab goggle when handling. 2. The relative centrifugal force (RCF) is calculated in g as follows: RCF = 1.12 x r x (rpm/1,000) 2 Where r is the radius of a rotor in cm, and rpm is the speed of the rotor in revolutions per minute. 3. Buffer 2 (1 st Washing) and Buffer 3 (2 nd Washing) are supplied as concentrated solutions. Before using for the first time, add absolute ethanol as indicated on the bottles. 4. To inhibit RNase activity, we recommend adding β-mercaptoethanol to Buffer 1 (Binding) before use. Add 10 µl β-mercaptoehanol(>99%) per 1 ml Buffer 1 (Binding). Typical Yields of Total RNA Cell type (1x 10 6 ) Hela 293T Balb/c 3T3 Huh7 Yield 10~15 ug 20~30 ug 20~30 ug 10~15 ug (Note) We recommend using our MagListo TM Magnetic Separation Rack for guaranteed results. 6

10 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

11 6. Place the tube in MagListo TM -2 (micro/mini)/ MagListo TM -15 (midi) scale separation rack with the magnet plate attached and invert the tube 3~4 times gently until the beads tightly bind to magnet. * How to Use - Attachment 1 1 Attachment: Combine the magnet plate to the stand. - Discard solution 2 2 Discard solution: Discard solution by inverting the MagListo rack. The silicone immobilizer inside the stand holds the tubes from falling in an upside down position. When discard solution, invert the rack completely for the solution not to smear on the rack. - Detachment 3 3 Detachment: Push up the magnet plate gently. 7. Keeping the tubes from MagListo TM rack, discard the supernatant and remove the remaining supernatant using a paper towel by blotting. Washing 8. Detach the magnet plate from MagListo TM rack. Add 350 µl for (micro)/ 700 µl (midi)/ 3.5 ml (midi) scale extraction of Buffer 2 (1 st Washing) to the tube. Close the cap and 8

12 mix by Votexing or Shaking until the bead are fully resuspended. 9. Place the tubes in MagListo TM rack with the magnet plate attached and invert the tube 3~4 times gently until the beads tightly bind to the magnet. 10. Maintaining the tubes in the MagListo TM rack, discard the supernatant and completely remove the remaining supernatant using a paper towel by blotting. 11. Detach the magnet plate from MagListo TM rack. Add 350 µl for (micro)/ 700 µl (midi)/ 3.5 ml (midi) scale extraction of Buffer 3 (2 nd Washing) to the tube. Close the cap and mix by votexing or vigorous shaking until the bead are fully resuspended. 12. Repeat the above step 9~10 for additional washing. 13. Detach the magnet plate from MagListo TM rack. Add 350 µl (micro)/ 700 µl (mini)/ 3.5 ml (midi) of absolute ethanol to the tube. Close the cap and mix by votexing or shaking until the bead are fully resuspended. 14. Repeat the above step 9~10 for additional washing. Drying 15. With a heat gun or a blow dryer, completely dry the beads with the tube open 3 cm away from the top of the tube. (micro/mini : >1 min, midi: >3 min) (Note) Alternatively, the beads can be dried with a dry oven at 65 for current times. (micro/mini: >5 min, midi: >25 min) Please use the Clean Bench during the drying procedure is recommended to prevent RNase or other aerosol contamination. Elution 16. Add for 80 µl (micro/mini), or 250 µl (midi) scale extraction of Buffer 4 (Elution) to the tube with the magnet plate detached and resuspend by Votexing or pipetting 17. Incubate the tube at 50 ~65 for 2 min. (Note) Warm up the tube with a heat block, a heat gun or a blow dryer. 18. Vortex the tube for 15 sec. 19. Attach the magnet plate to MagListo TM rack and invert the tube 3~4 times gently until the beads tightly bind to the magnet. 20. Without removing the tube from MagListo TM rack, carefully take the supernatant containing RNA to a sterile microcentrifuge tube. 21. Discard the used Magnetic Nano Beads. Do not reuse the beads. 9

16 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.
