Because of staffing changes, there will be some short-term changes to the calendar for the URMC FCC. We apologize in advance for any inconvenience and will work with you to minimize the impact of these short-term changes while we bring new staff up to speed.

Briefly through January 1st (or sooner if everyone is up to speed):

  1. All instruments will be down on Monday's till noon for the weekly long-cleaning and QC
  2. Sorters will shut down on Friday at 4pm
  3. Evening sort hours will only be available Tuesday-Thursday.

If you have any concerns, please contact either Matt Cochran or Tim Bushnell to discuss these short-term changes. We will be back to full complement as soon as possible.

20 September 2012

Dr Bunsen's Suggested Voltages have been updated to reflect the recent change in instrument baselines. I would also like to take this opportunity to welcome our newest muppet to duty, Rowlf. He is an 8-color LSRII residing in 3-4151.

2 May 2012

To echo Tim's email sent earlier today about sorting:


As a reminder from our April 13th email to the list, we have implemented a
new sort form request that MUST be filled out and APPROVED before sorting.

On May 7th, if a sort has not been approved, the sort will not be performed
and you will be billed for the time reserved.

The form that Tim speaks of can be found here. Please be sure you are familiar with this form, and if you are not please contact either Tim or Matt to discuss the issues you are having.

23 April 2012

After all the work Fozzie had done last week, there was a need to redo his Peak 2 voltages. This information is now posted on his instrument page, and the new baseline is also in the library if needed.

13 April 2012

Over the weekend, our new database and sorting system will be rolled out. Please be sure to read the cytometry listserv announcement that Tim sent out earlier today. As always, feel free to stop by or let us know if you have any issues.

19 March 2012

The library page has been updated slightly to provide a question guided approach to locating information on the website. If there is something you routinely have to hunt for, please let a staff member know so the page can be updated!

2 March 2012

The next two training lecture dates have been posted. This coming Monday is the soonest. Also, there are two new instrument guides in the Library. One for FACSDiva, and one for the ImageStream. Give them a read if you are hungry for information!

6 February 2012

In an effort to streamline the data on intrument configuration pages, the linear ranges of PMTs has been removed and a link to each instrument's baseline report can now be found on the top of it's page.

3 February 2012

After a long delay, the seminar from January 9th is now available on the lectures page.

Also, two new forms have come online. The Change of Information form is for use then information tied to your account has changed. This would be account numbers, labs you work in, or if you are leaving the university. The second form is a Data Recovery Request. This form is to be used if you wish to recover data older than two months since it will no longer be on the local machines. Please fill out that form and the rest will be take care of. As always if you have any comments please feel free to contact a staff member. Thanks!

Thank you.

9 November 2010

Two messages from Tim:

We are considering offering a week-long course at the URMC for
investigators to get trained in flow cytometry. The course would cover cell
preparation methods, data acquisition and analysis with flowjo, as well as
an introduction to others techniques (such as Luminex, the imagestream, cell
sorting and the like). Lecture topics would cover all aspects of flow
cytometry - from how the instrument works to designing experiments and many
topics in between. This course would cost about $400, to cover our costs,
and would be limited to 16 students.

The first course would be offered in January, if there is sufficient
interest. To gauge that interest, please contact me if you are interested,
and the level of interest (definitely take course, probably take course or
just interested) by November 19th.

The draft course outline can be found here.


I am pleased to announce that there will be a seminar on the new CyTOF cytometer on Friday, December 10th, at 12 noon in K-207 (2-6408). Dr. Vladimir Baranova will give a short talk on the technical aspects of this new technique. This will be followed by a longer biological applications talk by Dr. Olga Ornatsky.


This exciting new technology is one being considered by the flow core as a target for a Shared Instrument Grant in 2011, and the Rochester Human Immunology Center is working with the FCC and DVS (the makers of the CyTOF). There are only a few labs currently using this technology, and it brings the possibility of high-end (30+) marker detection to cytometry.


The abstract for the talk can be found here.

1 November 2010

The instruments page has been updated to better categorize the guidelines for our instruments.

The useful links page has also been updated and categorized.

29 December 2008 - A message from Tim:

I am pleased to announce that the move from MBX 1-11314 to 3-4100 has gone smoothly. The 12-color LSR-II, FACSCanto, FACSCalibur and Imagestream all survived the trip and appear to be working well. We are in the process of validating and characterizing the instruments after their move and realignments.

Starting this week, we will have limited hours in the lab, based on staffing and such.

One important issue that is being addressed now is access to the 3-4100 area. At present and through at least 1/8/2009, the flow core will operate under reduced hours (9 am to 5:30 pm). The reason for this is that we do not have card-swipe access to our facility yet, and do not have sufficient keys to provide individual labs access. We are working with the keyshop to resolve this issue and hope to have card-swipe access on the main door and two analytical rooms (3-4151 and 3-4141) within 2 weeks.

Cell sorting will still be occurring in MRBX 1-11314, and we are working with Janet Ives to develop the new protocols that will be in place to comply with the IBC guidelines. Once those are finalized, I will notify the community as to them.

As always, if you have any questions or comments, please don’t hesitate to contact me directly.


Attention Flow Core users:

The core will be shutting down to move on December 22nd. ALL of the instruments in MRBX 1-11314 will be offline for that week. If there are any concerns, please talk to Tim sooner than later so that no problems that arise.

As a note to all Core and HIC user: There is now a reservation system for the HTS units that work in combination with any of the LSRIIs. These can be reserved in the same manner as an instrument found on the online calendar.

An update on the location of the Flow Core:

Renovations to the 3-4100 area are underway as of September 22nd. More information about a possible moving day will be posted as the time draws closer.

A note to users of the FACSVantage instruments:

These will be going offline as of August 1, 2008. Please make sure to familiarize yourself with the FACSAria and Diva software utilized by the Flow Core. It is also recommended that you validate any protocols on the FACSAria before experimentation is done. Please contact Tim if you have any further questions.

Additional information about the billing system in use has been added to the Billing link on the left panel. Please review the new information and speak with Tim if there are any questions or concerns.

The 12-color LSRII in the Flow Lab is now online! The laser configuration is the same as the 11-color LSRII in the HIC with the exception of the Violet laser. Head over to the Analysis page to find information about this difference. Reservations can be made here as well.

The new FACSCanto is on-line and available for use. This is an 8-color insturment running DIVA 6.1. You will need a log-in account. If you do not have one, you will need to apply for one here.

Our new calendar is on-line. Please bookmark You will need a log-in to make reservations. You can apply for one here.

We will be bringing on-line a new 12-color LSR-II in early June.
