Alexa Fluor® Conjugated Secondary Antibodies

Superior photo- and pH-stable fluorescent dyes for multiplex analysis

Fluorescent labelled antibodies are widely used for flow cytometry, cell imaging and frozen sample immunohistochemistry. When used, the dye in the antibody gets excited at a set wavelength and then emits a photon at a different wavelength, that can be detected by a fluorescent microscope, allowing a signal amplification detection of the primary antibody used.

The Alexa Fluor dyes can be conjugated to a wide variety of secondary antibodies and possess low species cross-reactivity, making this type of antibody suitable for complex multi-colour analysis.

These dyes offer superior photo and pH stability alongside higher brightness when compared to the dyes that they have been synthesised from.

We offer a wide variety of superb Alexa Fluor conjugated secondary antibodies covering a range of wavelengths.
