Flow Cytometry Antibodies

Proteintech antibodies are conjugated to a variety of dyes so you have flexibility in building your panel. Some antibodies are offered unconjugated as well so you can pick whatever dye works best for you.

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

Directly conjugated antibodies can help build faster, easier flow cytometry panels. Our flow cytometry validated antibodies are conjugated to a variety of fluorophores including, FITC, PE, APC, and our very own CoraLite dyes. Our CoraLite 488, CoraLite 594, and CoraLite 647 dyes have equivalent brightness to Alexa dyes and provide long-lasting fluorescence. The CoraLite dyes can easily be multiplexed with other popular dyes due to minimum overlapping fluorescence spectra.

CoraLite® Plus Dyes

CoraLite plus dyes are Proteintech’s new range of fluorescent dyes particularly for Flow Cytometry studies. They offer more intensity brightness than other CoraLite dyes and traditional dyes and are suitable for multiplex Flow Cytometry analysis.

OKT4 CoraLite plus 650 conjugated antibodies showing strong signal during flow cytometry analysis

OKT4 antibody was conjugated to CoraLite647 and CoraLite plus 650 dyes, respectively. From left to right: 0.0625ug, 0.125ug, 0.25ug, 0.5ug antibody staining to human PBMC, lymphocytes are gated (Blue: CL647-OKT4; Red: CL650-OKT4). CoreLite plus 650 dyes show stronger signal than CoraLite647 dyes during Flow Cytometry analysis.

Proteintech now is offering CoraLite plus 650 conjugated antibodies for Flow Cytometry use. View all CoraLite plus dye conjugated antibodies.
