Flow Cytometry Reagents
Gain quantitative single cell insights with flow cytometry and FACS reagents that come with the dependability and quality scientists expect from RayBiotech.
Manufactured in our US-based facility for supply chain reliability and backed by our expert technical support scientists, you can confidently advance a wide range of flow cytometry and FACS projects with RayBiotech.
Bright dyes, quality antibodies, reliable kits
Whether you’re looking for a tagged secondary antibody that can deliver low background binding and high signal-to-noise ratios, an unlabeled primary antibody, a cell viability marker that won’t overlap with your existing panel, or a convenient kit that includes a complete set of reagents, you can find it at RayBiotech.
A focus on quality
At RayBiotech, we understand how variable biology can be and strive for consistency in every product we manufacture. With our flow cytometry reagents, this is reflected in our quality control studies which include using flow cytometry to test every batch instead of faster, simpler western blots. This way we can verify performance in your intended application.

What customers are saying
“Kelly was helpful all along with the technique, sample preparation, and data analysis. Although Ray is a commercial company there was no tendency to hide information. The experience was just like collaborating with an academic research lab.”

Featured Service
Flow Cytometry Reagents Services
Our experienced flow cytometry service team can help you evaluate a wide range of cellular processes, quantify cell populations, and even shed light on intracellular signaling events.
Basic Flow Cytometry Protocol
Cell Preparation
Gently harvest and wash cells, preferably with ice cold (4°C) reagents to preserve cell physiology.
Sample Blocking
Incubate suspended cells in a blocking buffer to prevent non-specific binding of primary antibodies
Antibody Incubation
Perform primary and secondary antibody incubations with dilutions based on cell concentration.
Data Acquisition
Run your sample through the flow cytometer and analyze your data.

Frequently Asked Questions

Antibodies for flow cytometry allow scientists to detect specific antigens and characterize the proteins on the surface of cells. Similar to other immunoassays, antibodies used in flow cytometry can be directly labeled with a fluorescent dye or bind to a secondary antibody carrying the fluorescent marker. The specialized nature of antibodies enables flow cytometry to detect different cell types according to their fluorescent color, each representing an antigen-antibody interaction.
Yes. In fact, discriminating between viable, living cells and non-viable dead cells is crucial for accurate flow cytometry analysis. The presence of dead cells in your samples may cause your antibodies to bind non-specifically, leading to false positives and skewed results. Therefore, when analyzing your results, make sure you distinguish between whole cells and cell debris for accurate results.
Any suspended cell or particle between 0.2 and 150 micrometers can be used for flow cytometry.
The most common samples for flow cytometry include:
- Non-adherent cells from culture
- Waterborne microorganisms
- Bacteria
- Yeast
- Bone marrow
- Peripheral blood with red cells removed by lysis
- Other body fluids
