Author Date Version SOP # Stephanie Swift January 2014 1 G003 Objective: This SOP addresses the maintenance and upkeep of the FACSCanto flow cytometer SOP-G003: FACSCanto Maintenance Schedule and Frequency A B C D E Maintenance System Initialisation Fluidics Cleaning Empty Waste Laser System Flush Frequency Before Use After Use When Full Weekly Bi-Monthly Note: to improve cytometer performance and minimise clumped cells in your sample population (which will falsely skew your data), all samples should be filtered through 48um nylon mesh before running on the flow cytometer. A. SYSTEM INITIALISATION 1. Turn on FACSCanto flow cytometer using the green button on the front of the instrument. 2. Open Diva software and check to ensure that the FACSCanto flow cytometer is connected to the computer. 3. Perform fluidics start up (approx. 10 mins.) 4. Wait at least 30 minutes for the lasers to warm up and stabilise before running samples. 5. Perform Cytometer Setup and Tracking (CST) (should be performed by an admin user at the beginning of the day, before running any experiments). Invert the CS&T bead tube several times to mix and add 1 drop of CS&T beads to 400ul of sheath fluid in a 5ml polystyrene tube. In DIVA, select CS&T, confirm that the bead lot number is the same as the lot selected on the screen. Place the CS&T bead mixture on the SIP and select run on the cytometer. Upon completion select use CST settings. Note: Each new lot of CS&T beads has to have a baseline tracking set-up before they can be used. This, like the CS&T itself, can only be done by an admin user. This protocol is shared by the Stojdl Lab under a creative commons license. B. FLUIDICS CLEANING 1. At the end of each use, wipe the SIP clean. 2. Install and run a tube containing 3 mL of a 1:10 dilution of bleach on the SIP. Allow the sample to aspirate for approximately five (5) minutes. 3. Remove tube, then install a second tube containing 3 mL dH2O on the SIP. Allow the vacuum to aspirate approximately five (5) minutes. 4. Repeat step 3 with a third tube containing 3 mL dH2O. 5. Place the instrument on STNDBY and continue with Shutdown if needed (i.e. if nobody is running less than 2 hours after you). C. EMPTY WASTE Empty waste containers as required (the machine will prompt you when emptying is necessary), and make sure 10% bleach is added into the waste container before it gets replaced on the wet cart stand (enough to cover the bottom of the container). a) Place instrument on STANDBY before disconnecting waste. b) Disconnect orange pressure tubing by pressing on the metal tab. c) Remove the cap at the sink in the room and pour the waste down the drain while running water to flush the drain. d) Add fresh bleach to cover the bottom of the container. e) Re-connect the tubing when finished. f) Use appropriate lifting technique for waste container. D. LASER MAINTENANCE To extend the life of the lasers, turn on the instrument for 3 – 4 hours at least once per week. E. SYSTEM FLUSH PROCESS An overall fluidics cleaning is required to remove debris and contaminants from the sheath tubing, waste tubing, and flow cell. Perform the system flush at least once every two (2) weeks. Note: Do not run detergent, bleach, or ethanol through sheath filter, this may break down the filter paper within the filter body, causing particles to escape into the sheath fluid, possibly clogging the flow cell. 1. Remove sheath filter (bypass filter). 2. Empty sheath container and rinse with deionized water. This protocol is shared by the Stojdl Lab under a creative commons license. 3. Fill sheath container with at least 1 liter of a 1:10 dilution of bleach or fullstrength BD FACSClean™ solution. 4. Empty the waste container it is ≥ ¾ full. 5. Install a tube with 3 mL of 1:10 bleach or full-strength BD FACSClean™ solution and acquire data on high for 30 minutes. 6. Remove tube and depressurise the sheath container by lifting the pressure relief valve cap. 7. Empty sheath container and rinse with deionized water. 8. Fill sheath container with BD FACSRinse™ solution. 9. Install a tube with 3 mL of full-strength BD FACSRinse™ solution on the SIP. 10. Repeat steps 5 – 7 with BD FACSRinse™ solution. 12. Fill sheath container with at least 1 liter of deionized water. 13. Repeat steps 5 – 7 with deionized water. 14. Replace sheath filter and refill sheath container with sheath fluid.
