Dr Gareth Howell setting up a cell sort on the BD Influx Cell Sorter in the CTF building flow cytometry facility laboratory


Welcome to the pages of the flow cytometry core facility within the Faculty of Biology, Medicine and Health at the University of Manchester.

Our facility offers researchers access to state-of-the-art flow cytometry analysis and sorting equipment, high parameter mass cytometry and imaging cytometry. The facility is managed full time by an experienced Senior Experimental Officer and is supported by two technical level staff.

We have available 6 flow cytometer analysers and 2 cell sorters. Additionally, we have a Helios-CyTOF for suspension mass cytometry, Hyperion Imaging Mass Cytometer and an ImageStreamX. Details of these instruments can be found in the links above.

Please contact Dr Gareth Howell (Facility Manager) for further information relating to accessing the facility.

Accessing the Facility

Register your account

In order to access the booking form and equipment calendar you will firstly have to register your details with the PPMS booking system

This can be accessed at http://tinyurl.com/bookflowcyt

You will be required to create a project after your registration has been accepted. You will then be able to request training, book the analysers or order services (cell sorts, submit samples to run on the CyTOF etc).

Analysis equipment

Firstly, contact the Facility Manager Dr Gareth Howell either by email (gareth.howell@manchester.ac.uk) or drop into his office in the CTF Building for a discussion about your project and what you hope to gain from using flow cytometry technology.

Training is then arranged one-to-one on the most appropriate system and is best performed with the researcher's samples as this will provide the most contextual training experience.

Once the above stages have been completed the user will be given access to the online booking system for the instrument(s) they were trained on and can access these systems whenever the require.

Detailed information about the equipment we have in the Facility can be accessed under the 'Equipment and Systems' page linked above.

Sorting equipment

Cell sorting is undertaken by trained facility staff (Dr Gareth Howell (CTF building) and Mr David Chapman (Michael Smith building).

Sorting appointments are arranged at a mutually convenient time following discussion with the sort operator.

Researchers will then be required to submit an 'Order' through the PPMS system which will then be accepted by the operator.

Following the sorting experiment the operator will edit the sort order and submit this to finance.

Details regarding sample preparation etc can be found on the cell sorting page

Data Analysis

Flowjo

We use Flowjo to perform third-party data analysis of the data produced in the Facility.

For more information and training resources on Flowjo please visit the website at http://flowjo.com

We have a number of Flowjo dongles that are available for loan from the Facility.

Please contact us for further information.

Workshops and Training

We run a series of in-house training workshops on all aspects of cytometry.

  • New User Training on Analysers

New users will be requited to attend a laboratory induction session where local rules and building health and safety are covered.

One-to-one training on operation of the analysers will be arranged s required and is detailed in the 'Accessing the Facility' section above.

  • TechnoShort workshops

These are a series of 3-hour long workshops that over consecutive weeks cover the following topics:

  • Introduction to flow cytometry

  • Multicolour panel design

  • Compensation in flow cytometry data

Classes are restricted to 8 attendees due to space in the lab

  • Imagestream workshop

We are planning to provide an introduction to the Imagestream technology in a workshop.

Please e-mail Gareth if you are interested, and updates will be posted here


Resources

Panel Design

Please contact the Facility to discuss any panel design questions you may have.

We also run a short workshop 'Multicolour panel design' as part of the Technoshort series of workshops (detailed above).

To aid in panel design please read below about published optimized panels (OMIPs)

Flurochrome Brightness Index

Not all flurochromes are the same and one of the challenges of designing a multicolor flow cytometry experiment is balancng the anticipated expression level of the antign with the relaive brightness of the flurochrome. To aid this there are 'Brightness Index' tables where the relative brightness of common flurochromes are given.

OMIPs (Optimized Panels)

Optimized Multicolor Immunofluorescence Panel (OMIP) is a special peer-reviewed Cytometry Part A publication type that reports on newly designed and optimized multicolor panels for flow cytometry, fluorescence microscopy, image cytometry, and other polychromatic fluorescence-based methods. The first two OMIPs were published in the September 2010 issue of the Journal.

OMIPs are aimed: (1) to alleviate the development time for researchers in need of the same or highly similar panels, (2) to provide a starting point for the creation of novel OMIPs, and (3) to give the developers of the panels credit via citation or the publication.

An OMIP consists of two portions:

i. A two-page printed component includes basic information, such as the title, a summary table, a brief narrative, a reagent table, an example staining figure and a detailed comparison with similar OMIPs.

ii. An online component includes significant amount of technical details, such as panel development strategy, cross-references to related panels, exact staining protocol, instrument configuration and reagent information.

For more information on OMIPs, please refer to the following articles:
