Flow Cytometry Services

Fill out the service form and include it with your shipment to RayBiotech. Cells should be in the appropriate amount of dimethyl sulfoxide (DMSO) and shipped frozen (on dry ice).

1. Aliquot the cells into cryovials containing cell culture media and dimethyl sulfoxide (DMSO) at the desired cell concentration. The appropriate amount of DMSO depends on the cells, but is usually 5 - 10% (v/v).
2. Slowly freeze cells to maintain cell viability. You can either place the cryovials in a controlled rate freezing apparatus (decreasing the temperature approximately 1°C per minute) or in an isopropanol chamber overnight at -80°C.
3. Store the cells in the gas phase in a liquid nitrogen tank.
4. Ship the cells on dry ice. Ensure that there is enough dry ice to keep the cells frozen during shipping. Please ship your samples overnight on Monday through Wednesday only. Learn more about how to ship samples by clicking the SAMPLE SHIPMENT INSTRUCTIONS button below.

Flow cytometry offers the advantage of analyzing thousands of cells per second, providing high-throughput data across multiple cell surface or internal parameters on a single cell. This enables detailed characterization, enumeration, and phenotyping sorting of heterogeneous cell populations.

As offered from RayBiotech directly, these flow cytometry based services and products are for Research Use Only (RUO). If interested in diagnostics, reach out to our team directly, as it is possible to validate assays and services for your diagnostic needs.

Flow cytometry requires single-cell suspensions, which may not be suitable for all sample types. Specifically, there are limitations in resolving very small particles and detecting rare events in highly complex mixtures without running a large amount of material through the cytometer.
