In order to sign up to use machines, you have to be formally trained by the facility. You cannot train others in your lab to use the instrumentation.

Once you are trained and allowed access to the calendar, you can book time online.


  • The CytoFLEX LX, LSR II, Gallios, and the Celigo are available 24 hours/day, 7 days a week.
  • All users are required to sign in on the on-line calendars before using the instrumentation.
  • To access these machines, post training access, card programming, and authorization forms are available from the flow facility.


You need a Proxy card to gain access to the Flow Core Facility. After receiving authorization from the Flow Core, you can get a Proxy card through the Public Safety Office or have your current Proxy card activated.

  • Controls are required for your sort and should include a negative, or unstained control, and single-stained positive control for each fluorochrome you are using. -Sterile collection tubes with media added/extra media (sorting is aseptic, we are not located in a sterile room, therefore no guarantees of sterility).
