Flow Cytometry Antibodies

a graphical representation of an antibody’s interaction with antigens, featuring a yellow Y-shaped structure on a purple background with green dots at the tips, and colored lines suggesting different pathways or interactions.

Flow cytometry analysis is a technique commonly used to examine physical and chemical characteristics of cells and particles. Antibodies are used in flow cytometry to help characterize markers on the cell surface since they allow for the detection of specific antigens. These antibodies can be directly conjugated to a fluorophore (direct detection) or paired with a fluorescently labeled secondary antibody (indirect detection). By adding specific fluorophores to specific antibodies, cells can be sorted and analyzed simultaneously.  

For successful flow cytometry assays and reproducible results, antibodies validated for use in flow cytometry and proper controls are essential. We offer high-quality flow cytometry validated primary antibodies, secondary antibodies, and isotype control antibodies to support all your flow cytometry needs.
