5 steps of the flow cytometry panel builder

Following 5 simple steps, anyone can design a flow cytometry panel. Whether they are new to flow cytometry or experts in the field, the panel builder can help.

Cytometer configuration



Antigen selection





When you are done, click on the Next Step button.

Fluorochrome selection

Fluorochrome selection is guided by the spectral information of each fluorochrome. This step allows you to visualize the spectra of selected fluorochromes across the top of the page as you select fluorochromes for each antigen shown on the left.

Before any selection is made, the number of available channels for each antibody is shown. With each antigen selection, another spectrum will show at the top of the page. A matrix view allows you to see the antigens listed in the rows and with the channels shown in the columns.

A black flag in the corner indicates the recommended fluorochrome choice based on protein abundance from step 2.


Begin making fluorochrome selections. Start with the top row which lists the antigens with the fewest fluorochrome options available. Work down the table to the antigens with the most fluorophore options on the bottom. To guide you in fluorochrome selection, spectral information is provided. In general, the least spectral overlap is best.

Continue selecting your options to match all antigens with a fluorochrome. When done, check that your choices will work for your instrument by clicking on the SpectraViewer button.

Invitrogen Flow Cytometry Panel Builder FAQs

  1. Can I go back a step without losing the work I did?
    • Yes, the previous work is saved.
  2. My marker isn’t showing up under step 2 of antigen, but I see it in the catalogue. How can I remedy this?
    • Select your target species first, and then type your antigen.
  3. How do I share my panel with my lab manager?
    • Export the spreadsheet found on step 5.
  4. What do the colorful dots indicate in the “Fluorochromes” step?
    • The dots indicate the number of fluorochromes that Thermo Fisher Scientific has available in each channel on the cytometer you have chosen.
  5. My cytometer does not use a standard configuration. How can I make changes to one in the dropdown?
    • Select a cytometer from the dropdown menu and then select the “Edit cytometer settings” link to modify the configuration as needed.
  6. I can’t find my cytometer in the dropdown. Can I build one?
    • Yes, you can define a new cytometer using the “Enter your cytometer manually” link below the cytometer dropdown menu.
  7. I do not order products through thermofisher.com. What other endpoints are available to me?
    • There are both PDF (printable) and CSV (spreadsheet) exports available in the summary step for you to take away for reference and ordering purposes.
  8. I plan to use antibodies that are not from Thermo Fisher Scientific. How can this Panel Builder be useful to me?
    • Step 2 allows for antibodies you already purchase or from outside Thermo Fisher Scientific. If you are undecided about which format you want for something, you can add the antigen name in the “Antibodies you need” section and then choose a placeholder fluorochrome in the following step. Both will help you keep track of channels that are reserved for reagents that you do not plan to buy from Thermo Fisher Scientific.
       

Tips for picking fluorochromes

Fluorophores emit light with varying levels of brightness (Figure 2). When choosing fluorochromes on the panel builder, we suggest:

  • Use a staining index for your specific flow cytometer. A staining index can be provided as a chart or table from a manufacturer who tested the same clone with different conjugates on their instrument. It is also possible to create a staining index with flow capture beads. For example, Figure 2 shows a staining index of the most popular fluorochromes analyzed on the Attune NxT Flow Cytometer. Each flow cytometer has different lasers, filters, and detectors that can influence the signal observed from a marker conjugated to a fluorochrome.
  • Chose a combination of fluorochrome brightness based on your expressed protein levels. Using only very bright fluorochromes may result in spillover and can dampen the signal of a marker.
  • Examine the mean fluorescence intensity for each fluorochrome and antibody clone to compare brightness. These can be found in product data sheets.

Tips for antigen density or protein abundance

Knowing your protein abundance will help you determine the best fluorochrome. Very bright fluorochromes are best used for low-abundance targets. Dimmer fluorochromes are fine for use with high-abundance targets. We advise:

  • Gene expression levels may vary depending on cell source, stimulation, and protocols used for fixation.
  • Dim fluorochromes to detect highly expressed proteins and bright fluorochromes to detect less-abundant proteins.
  • Use flow cytometry compensation beads to help determine the specific density of your antigen. Internet-accessible databases can also help to find RNA expression levels.

Tip 1: Minimize spill-over by using the correct and separate channel

Any time you have markers that you know will be co-expressed on your cells of interest, make sure to space them out into separate channels. If you will need to use any adjacent channels, that's where you would put any markers that are mutually exclusive so that they'll still be easy to distinguish.

Tip 2: Intracellular targets need special buffer for fixation and permeabilization for staining

You'll also want to keep in mind the buffer that you're using to fix and permeabilize your cells, as we have several options. When you're looking at cytoplasmic targets, what the buffer is appropriate may not be the same as when you're looking at nuclear targets, because you want to make sure that you still have access to your antigens without over-fixing your epitopes.

Tip 3: Viability dyes are required to find live cells

A third tip I wanted to share with you is to always include a viability dye in your staining panel. This will help eliminate any false positives that are caused by dead cells or debris, because those can be sticky. You have a lot of options for choosing a viability dye, so you don't need to design your panel around them. You can build out the rest of your panel and optimize your core markers, and then fit in a viability dye in an empty channel.

Tip 4: Save your bright fluorochromes for dim targets

As you're building out your basic panel and you want to incorporate some more antigens, make sure you're keeping the density of your antigen expression in mind. So if you have antigens with low or unknown expression, those would be ones that you want to assign to your brightest dyes, such as PE or APC.

Tip 5: Try to combine negative markers in one channel (dump channel) to save space on your panel

A helpful trick when you want to exclude a lot of cell types at once without having to suck up multiple channels for that would be to use a dump channel. This is where you're placing all the antibodies that identify your cells that are not of interest into the same channel with the same fluorochrome, and then those can be easily gated out and all of the cells negative for the dump channel would be those that you use for your analysis going forward.
