Flow Cytometry Antibodies

Top-cited clones and Proteintech’s in-house clones have been conjugated to a variety of dyes for ease of staining and to reduce the length of your protocol. Unconjugated antibodies are also available to give you the most flexibility in building your panel.

Flow Cytometry Antibodies

Conjugated and unconjugated primary antibodies validated for use in flow cytometry experiments.

Intracellular Flow

Products for labeling intracellular proteins including fix & perm buffers and antibodies that are conjugated to a range of fluorophores.​

Supporting Reagents & Kits

Reagents to support your flow cytometry experiments: fix & perm buffers, isotype control antibodies, secondary antibodies, viability dyes, and more.

Isotype Controls

Experimental control antibodies to determine any background or nonspecific staining due to immunoglobulin class and subclass of the primary antibody.


Resource center with protocols for labeling of intracellular and extracellular proteins, multicolor panels, and other types of flow cytometry analysis. ​

Spectra Viewer

Plan and design your multicolor panel experiments using our Spectra Viewer to view excitation and emission of different fluorophores.

Available Fluorescent Dyes

Our flow cytometry antibodies have been conjugated to traditional flow cytometry dyes like FITC, PE, and APC as well as our CoraLite® Plus fluorescent dyes. CoraLite® Plus dyes range from 405nm to 750nm and have excitation and emission wavelengths similar to AlexaFluor® dyes and can be easily multiplexed with other popular dyes. Can’t find the color you need? Our FlexAble antibody labeling kit can be used to conjugate one of our CoraLite® Plus dyes to the unconjugated antibody you already have.
