Secondary Antibodies

Secondary antibodies are monoclonal or polyclonal antibodies that bind to primary antibodies attached to specific proteins, allowing for the detection, purification, amplification, or sorting based on the presence of specific antigens.

We offer a broad range of unconjugated secondary antibodies, as well as secondary antibodies conjugated to fluorescent dyes such as DyLight® and Cy® dyes, FITC, HRP, and R-PE for a wide range of applications such as flow cytometry, ELISA, spatial biology, and immunofluorescence. We also offer enzyme-conjugated antibodies including biotin, and HRP, which can be used for signal amplification in western blot, ICC, IHC, ELISA, and more.
