Welcome to the听Flow Cytometry Core Facility (FCCF)!
Located in the Bellini Pavilion of the Life Science Complex, the Core facility provides instrumentation and technical assistance to perform laser-based flow cytometric analysis, as well as providing an operator based cell sorting service.
Please follow this link to access our external webpage for a complete description of our services, instrument details, available resources and core policies:听

The Flow Cytometry Core Facility is equipped with 4 different flow cytometers for various applications. An operator-based cell sorting service is also offered. You can refer to the equipment section of this website to view the instrument available. For a more complete description of the equipment (configurations and technical specificity), please consult our external webpage ().
We provide the mandatory two-part training for the users to gain access to the cytometers. An initially theory training needs to be taken by the new users (drop-in sessions every other Tuesdays in room 330 of the Bellini building; inquire the core staff about the next available dates). The training is concluded with a second part hands-on training on the desired instrument. We offer consultation for experiment design, data analysis and other technical assistance. Users or clients that won鈥檛 be doing regular acquisition and analysis can also ask for operator assisted data acquisition and analysis. We offer web-based portal subscriptions for the software FlowJo that can be purchased by labs for a yearly few.
The facility is open Monday through Friday from 9:30 a.m. until 5:00 p.m. for cell sorting services and user assistance. The cytometers are accessible at any time for trained users. Instrument training requests and cell sorting appointments need to be booked through the scientific platform admin system Infinity X. Details are explained in the Booking Calendar tab.

Beckman Coulter CytoFlex SRT
鈥 4 lasers (405/488/561/638 nm); 17 parameters; **instrument located in the GCI BSL-3 facility in a biosafety cabinet**
Cell Sorting and Sample Preparation
The sort can be performed at different pressure and nozzle size. We offer 4 different sorting conditions for various cell types:
-70 uM /70 PSI (Splenocytes/Thymocytes/PBMC/Whole blood/bone marrow)
-85 uM /45 PSI (Transduced-transfected splenocytes, thymocytes, bone marrow cells / B or T cell lines)
-100 uM /20 PSI (Fibroblasts, cultured primary cells, medium to large cell lines, endothelial cells, adherent cell lines, transfected cell lines)
-130 uM /16 PSI (Dissociated tumor cells/ large cell lines/ delicate- sensitive cells)
Please consult facility staff to decide the ideal conditions for your sort.
Note that the nozzle size and sample concentration will affect the time of your sort. The optimal threshold rate to achieve the best recovery/efficiency ratio will be the determining factor.
Basic Sorting buffer
Prepare the following buffer in which to suspend your samples after staining, prior to cell sorting:
1X Phosphate Buffured Saline (PBS) or Hanks Balanced Salt Solution (HBSS) (free of Ca2+ or Mg2+)
1 % heat-inactivated FBS (or BSA)
1 mM EDTA (can be removed for simple lymphocyte populations)
Sterilize with a 0.2uM filter and store the solution at 4掳C.
Before bringing your samples to be processed, filter them through a 40/70 uM mesh filter. Consider bringing extra buffer for dilution purposes.
Modifications for specific cell types:
For Sticky Cells: The EDTA concentration can be increased to 5 mM. Note that cell tolerance for EDTA varies; too much can kill your cells. FBS can neutralize adherent cells. Consider using cell dissociation products that maintain cell suspensions.
鈥
For sensitive cells: You can add 25 mM HEPES to stabilize the pH.
For samples with high cell death: DNA will be released in solution by the dead/dying cells. This significantly increases cell clumping. Add DNAse to your sample prior to sorting.
Sample Collection
Cells can be collected in various types of tubes or plates:
-Eppendorf tubes
-5 ml FACS tubes (ideally polypropylene as cells adhere less than in polystyrene)
-15 ml conical tubes (2-way sort only)
-Multi-well plates (6, 12, 24, 48, 96, 384) (1-way sort only)
-Slides (1-way sort only)
Coat the recovering tube/plate with media or PBS before arriving. You can add roughly 10-20% of the receptacle volume (e.g. 2ml in a 15ml conical tube). Consider adding a higher concentration of FBS to the recovery media for sensitive samples.
The collection tubes can also be kept at 4掳C during the sort. You can decide the collection temperature on the day of your sort and tell the operator.
To gain access to the facility and receive their initial training, new users will need to create their account on 苹果淫院鈥檚 scientific platforms administration system, Infinity X of which the FCCF is part of. Users can access the software using the link bellow:

Monthly billing by the FCCF will be based on calendar booking time. Users need to book the right amount of time needed on the instrument and adjust the actual used time afterwards on Infinity.
