Peak 6 Bead Information

The reference bead that is used in the facility is from Spherotech. We use the Rainbow Calibration Particles, 6th peak of 8. The part number for this product is RCP-30-5A-6 and the current lot that we use is AC01.

Connecting to the Transfer space

Double click the "shortcut to transfer" icon on the desktop of the instrument computer. An explorer window with a folder for each PI will open. NOTE - you will be able to view the contents of the folders but will not be able to read the contents of any of these folders, even your own. These folders are write only from the instruments. As before, drag the folders you want to transfer from the FCS folder to your group folder.

To recover your data on your lab computer:

For PC:

Windows 7:

Click "Start" then in the "Search programs and files" field type:

\\smdnas\FCC_Transfer\PILastName_FirstInitial (ie. bushnell_t)

If you've had Windows remember your credentials then you may have to delete
those. You can do this by clicking the "Start" button and then in the
"Search programs and files" field that appears type "credential manager".
You should see a suggested icon of a safe appear in the list above the
search field that says "Credential Manager". Click this, it will open a
new window showing your saved credentials. Under "Windows Credentials"
delete anything related to RDS01. If you are in doubt feel free to delete
a Windows Credential, the worst case scenario is you will have to re-input
your password for something else.

Windows XP:

Click "Start" and then "Run".In that field type

\\smdnas\FCC_Transfer\PILastName_FirstInitial (ie. bushnell_t)

For Mac:

Click "Go" in Finder, choose "Connect to Server" then type:

smb://smdnas/fcc_transfer/PILastName_FirstInitial (ie. bushnell_t)


smb:// (ie. bushnell_t)

If you are prompted for a username and password use your URMC
network credentials (what you would use for webmail or to log onto a
Windows computer here).


Data will be automatically removed from the transfer partition after two weeks.

Connecting to the Library Share

This is done similarly to the Transfer space. Here we have shared documents that are available to all registered users. This includes past lectures, IDEAS software, and other goodies.

For PC:

Start Menu >In the search menu type:


For Mac:

Finder >Go > Connect to server


If you are prompted for a username and password use your URMC
network credentials (what you would use for webmail or to log onto a
Windows computer here).

Grant Information

The URMC Flow Cytometry Core facility (FCC), under the direction of Timothy Bushnell, Ph.D., is a full service facility with approximately 1100 sq. feet of newly renovated lab space, employing a staff of 6. The facility currently has a range of digital flow cytometers including a 2-laser, 4-color Accuri C6, a 3-laser, 8-color BD-FACSCanto-II, two 3-laser, 12-color BD LSR-II’s, and two 4-laser, 18-color BD LSR-II’s. Additionally, the facility is equipped with a 3-laser, 13-color FACSAria-Iiu, a 4-laser, 18-color FACSAria-II, both of which are equipped with aerosol management systems, automatic cell deposition units, and are housed within Baker Bio-Protect-III biosafety hoods. The facility also has a 3-laser, 6-channel IS100 and 4-laser, 12-channel ImagestreamX imaging flow cytometers from Amnis. The facility has three dedicated analysis workstations for investigators with standard flow cytometric analysis software (Flowjo, IDEAS, Modfit). All data generated in the FCC is archived onto a 10-terabyte server with daily tape backup.

The FCC has established a series robust QA/QC protocols and procedures that are designed to ensure the instruments are performing optimally. These include standard quality control measurements, as recommended by the instrument manufacturers. Additional detailed instrumentation characterization and QC are performed based on best practices in the field. All QA/QC information is available to investigators and instrumentation characterization data is available on the FCC’s website.

All investigators go through a robust training program to allow them run the analyzers independently, allowing for experienced users to have 24/7 access. All booking is done via an on-line calendar system. All sorting is done by the FCC staff, and is available to investigators from ~10 am till ~8 pm daily.
