Resources for Experimental and Panel Design

The experimental design process, including proper panel design, is critical for the success of a flow cytometry experiment. We have assembled a variety of resources to help you through these often complex steps. In addition, we are always available to provide assistance through consultations and on-instrument guidance.

Sample Preparation

The quality of your sample will determine the success of your experiment. You must ensure that the sample is prepared as a robust single-cell suspension and is debris free. You must also ensure that cell viability is maintained during preparation and acquisition or sorting.

Protocols for preparation of blood, spleen, bone marrow and other immune tissues have been well-established and standardized. However, preparation of sample from solid tissue, often requiring mechanical and enzymatic disaggregation, is application-specific and must be optimized for the type of tissue you are working with.

It is best to start with a literature search or a protocol that has been established by someone in your lab or colaborator.

For further resources:

Reichard, et.al. have prepared a highly useful resource in Cytometry Part A for preparation of single cells from solid tissue:

Reichard A, Asosingh K. Best Practices for Preparing a Single Cell Suspension from Solid Tissues for Flow Cytometry. Cytometry A. 2019 Feb;95(2):219-226. doi: 10.1002/cyto.a.23690. Epub 2018 Dec 6. PMID: 30523671; PMCID: PMC6375754.

Miltenyi Biotec has also developed many products for gentle sample preparation.

Enzymes can be obtained from many sources. Wothington Biochemical has developed an Enzyme Manual and Tissue Dissociation Guide that are helpful in developing your protocol.

Panel Design

Panel design is the process of assigning fluorochromes to cellular markers. This process involves many factors, including compatibility of fluorochromes to the particular instrument you plan to use, fluorochrome brightness, considerations of spillover and spillover spreading, marker expression level, and autofluorescence of the target cells.

You can use the Panel Design and Optimization document as a starting point, and our staff can help you throughout the process.

Fluorofinder is a useful free online platform for panel design. All of the CSCI Flow Cytometry instruments have been uploaded to Fluorofinder. Please make sure to submit your panel for review before purchasing reagents.

Panel Design Services

In addition, antibody vendors, including Thermo Fisher and BioLegend, offer free panel design services.

  • You can find out more about Thermo Fisher's resource here. To begin the panel design process with Thermo Fisher, please contact the Panel Design Team.
  • Please contact Diana Vesely, Ph.D., Technical Application Scientist Lead, BioLegend, for more information about BioLegend's services.

Spectra Viewers

Spectra viewer online tools, which display the excitaton and emission spectra of commercially available fluorochromes in a user friendly format, are critical tools when designing flow cytometry experiments. You are highly encouraged to use one of the following tools when choosing reagents for any flow cytometry experiment, even those requiring only a few colors.

BD Spectrum Viewer

BioLegend Spectra Analyzer

Bio-Rad Fluorescence Spectraviewer

FPBase (spectra viewer for fluorescent proteins)

Thermo Fisher Fluorescence SpectraViewer

 

Sample Preparation for Cell Sorting

The sample requirements for cell sorting are more nuanced than for flow cytometry analysis alone. We have prepared a Cell Sorting FAQ that will help guide you when preparing for a cell sorting experiment.

Basic Protocols

BioLegend's Technical Protocols page provides a multitude of protocols for flow cytometry assays, including cell surface and intracellular antigen staining.

The Thermo Fisher Flow Cytometry Protocol Handbook covers sample preparation, immune cell stimulation, phenotypic analysis, cell viability and apoptosis, cell cycle, cell proliferation.
