The Gallios flow cytometer is an ultra sensitive high speed flow cytometer with 3 solid state lasers and 10 fluorescence colors. Its high stability and sensitivity allow very dim and rare populations to be accurately analyzed. Gallios has a customized forward scatter to achieve the most accurate size measurement and optimized electronics for high resolution and fast, accurate, and efficient processing.
The Gallios is the next generation flow cytometer from the existing Beckman Coulter FC500 flow cytometer in the Core facility. Data acquired by Gallios can be analyzed with Kaluza analysis software, which is available for users to analyze data on their own computers. In addition, data collected on the FC500 instruments can also be analyzed on the new Kaluza software.
The instrument can analyze particle size ranges from 0.4 µm to 40 µm diameter.

Tips for preparation of samples:
- Cell concentration in each tube: about 1 million cells/ml
- Sample volume in each tube: 0.3 – 1 ml (minimum volume is 0.3 ml)
- Sample tubes must be polypropylene (12×75 mm round bottom polypropylene tube- BD Falcon Cat# 352002 for non sterile, or Cat# 352063 for sterile).
- All samples should be filtered with 40 µm nylon cell strainers (Falcon # 352340) prior to running to avoid clogging the machines.
- If you have samples stained with more than one fluorochrome per sample, we recommend you bring single color stained positive control samples (each fluorochrome individually) and unstained or negative control (isotype) cells for proper compensation.
- We recommend that samples are kept on ice or chilled until ready to run on the instrument.
