The Gladstone Flow Cytometry Core enables scientists to analyze or isolate cells based on their phenotypic or functional properties, and can be used in conjunction with other core technologies to form a robust and effective pipeline for cellular analysis. Analysis of up to 18 and sorting of up to 15 fluorescent parameters is available from a wide variety of samples and cell types. Our staff is experienced in experimental and antibody panel design, practical operation of multiple flow cytometric platforms, and basic and advanced data analysis.

Discover how our core can help you with your flow cytometry needs.

FAQs

How Do I Book a Session on a Flow Cytometer or Cell Sorter?

You’ll first need to register for an iLab account. Once that’s complete, you should read, sign, and return the signature page of the general regulations document to the core by email.

Contact core staff if you have not used the core before.

Which Flow Cytometers Are Capable of Running Plates?

The Fortessa X-20, Attune NxT, and Cytek Aurora, are capable of analyzing 96- and 384-well plates.

How Do I Get Trained to Use the Flow Cytometry Core?

If you’d like to be trained on an analyzer or sorter, complete Gladstone’s Flow Core intro questionnaire to answer some questions about your experience, and email the core to schedule a date.

What Type of Samples Can Be Run on the Cytometer?

Any single-cell suspension where cells are between 500 nm and 20 μm can be run. Samples can be provided in 5-ml Falcon tubes, 15-ml Falcon tubes, Eppendorf tubes, multi-well plates, or slides.

Cells can be at a concentration of up to 5 million per mL in PBS or media, but serum should be limited to 2 percent serum, as more than this can affect the charge applied to the stream. You can also add HEPES (25 mM), EDTA (1 mM) or DNAse (10 U/ml) to avoid clumping. If you are concerned that your sample is too concentrated, bring in some media to dilute your sample. Filter your cells through a cell strainer or filter-top tube.

Can the Cytometers Be Used Independently, After Hours, or on Weekends?

After being trained, you must demonstrate proficiency in cytometer operation, maintenance, and basic troubleshooting before being allowed to use the equipment independently or outside of operating hours.

Does the Flow Core Archive Data?

The core saves a copy of the FCS files to an internal server.
