Training

Instrument Training

Hands-On Training is required of all new users after completion of the Introduction to Flow Cytometry class and and is instrument specific.  Training covers instrument operation, data collection, biosafety, troubleshooting, and general maintenance. Reserve 1.5 hours on the instrument of choice for Hands-On Training on the Flow Cytometers. Fluorescent Beads will be provided for training. Please do not bring cell samples.

For training on the ImageStream, please reserve 2.5 to 3 hours.  Training works best on this instrument with actual samples, so please bring experimental samples for your first training on the ImageStream.  This will provide an opportunity to assess sample prep, suggest steps for optimizing your assay going forward, and a data set to use for learning the IDEAS image cytometry data analysis software.

Training appointments are available at the following times:

  • ThermoFisher Attune (Lightning):  Tuesdays, 12-3pm
  • ThermoFisher Attune (Thunder):  Thursdays, 12-3pm
  • BD LSRII:  Wednesdays, 12-3pm
  • BD LSR Fortessa:  Reserve BD LSRII, Wednesdays, 12-3pm
  • MACSQuant10:  Fridays, 12-3pm
  • ImageStream:  Mondays, 12-3pm

After completion of Hands-On Training, users will schedule Assisted appointment(s) with actual experimental samples.  These Assisted appointments will focus on optimizing instrument settings for their specific experiments. Training will be complete when both the user and Flow Lab staff feel the user is competent to operate the instrument(s) independently.  Users will be checked off as trained in iLab for individual instrument(s) allowing user access to reserve instrument(s) outside of the reserved training times.

Additional Training

As part of our Educational Outreach Program, the UWCCC Flow Lab will come to your lab meeting, department meeting, journal club, class, or other group meeting to discuss topics of interest.  To schedule a seminar contact the Flow Lab. Our current list of common topics related to cytometry are listed below.  If you are interesting in something not listed please contact the Flow Lab at uwflow@uwcarbone.wisc.edu and suggest a topic.

  • Best Practices in Cytometry
  • Rigor and Reproducibility in Cytometry
  • Panel Design and Optimization
  • Overview of Computational Data Analysis Methods in Flow Cytometry

  • Data Analysis Basics
  • Getting Started with FlowJo
  • Getting Started with FCS Express

The Flow Cytometry Laboratory (Flow Lab) is approved by the Institutional Biosafety Committee to handle samples of biosafety level 2 (BSL2) and below. Cytometers create aerosols. All users must be able to provide the Flow Lab with a Biosafety Protocol number that indicates that all materials brought to the Flow Lab are at a BSL2 or lower and approved for use on a sorter or benchtop cytometer. Please contact the Biosafety Office if necessary.

The Office of Biological Safety and the Institutional Biosafety Committee are in the process of transitioning paper Biosafety Protocols into Bio-ARROW, the online Biosafety Protocol Form.

Samples exceeding BSL-2 cannot be analyzed or sorted in the Flow Lab unless the biohazards are inactivated through fixation. Please review our Flow Cytometry Standard Operating Procedures (pdf). All samples for sorting must be listed on your lab’s biological safety protocol and approved by the Office of Biological Safety.

If you have not used the Flow Lab before, see our FAQs about getting started, below.

  1. To use the Flow Cytometry equipment, you must make an appointment using iLab with your own account.  We do not allow users to make appointments for other users.  Abuse of this policy may result in removal of access to the Flow Lab instrumentation.
  2. Make note of the cancellation, no show and login password policies noted in the online scheduler. Remember that you may need a lead time of at least 96 hours for benchtop analysis and as much as two weeks for sorting. Plan ahead.
  3. We encourage all users to learn to run the benchtop cytometers themselves. Attendance at the monthly lecture series is required for all benchtop training sessions. Once you have the attended the lecture series, make an appointment for training.
  4. If you have not been trained to run the cytometers, or if you need assay-specific instruction, make an Assisted Benchtop appointment. Email us about experimental design, fluorochrome selection, and appropriate instrumentation.
  5. Access to self-appointments is restricted until you have completed training and are able to operate the instrument(s) independently.
  6. Rescheduling & Cancellation.  Any self-use reservation may be cancelled by the user up to 15 minutes before the start of the reservation at no charge.  Staff-assisted reservations, Training, Assisted, and Cell Sorting can be cancelled by the user up to 24 hours before the start of the reservation.  If cancellation is necessary within that 24 hour window, please call the Flow Lab at 263-0313 (WIMR) or 265-5547 (Biotech). No Call/No Show reservations are charged in full for time reserved.
  7. If you encounter scheduling difficulties or problems finding appropriate times for your experiments, always contact Flow Lab staff. We can help.
  1. The Flow Lab is staffed from 9am-5pm Monday through Friday. Requests for staff-assisted reservations for after-hours will be evaluated on a case-by-case bases and should be made well in advance.
