Alexa Fluor® Products

We have a broad range of Alexa Fluor® dyes and conjugates including secondary antibodies, primary antibodies, bioconjugates and more.  

Alexa Fluor® Secondary Detection Reagents

Alexa Fluor® secondary detection reagents exhibit superior brightness and photostability, outperforming conventional fluorescent reagents across the spectrum. Our conjugates are made with the highest quality antibodies and  avidins stringently tested on cell samples to ensure high selectivity and sensitivity. Most of our secondary antibodies have been affinity purified and cross-absorbed against the sera of a number of species to minimize cross-reactivity.

Alexa Fluor Dye Conjugates  
Alexa Fluor® Reactive Dyes
The Alexa Fluor® dyes are available in several reactive forms for labeling biopolymers and derivatizing low molecular weight molecules. All Alexa Fluor® dyes are available as an amine-reactive succinimidyl ester, and many are available in thiol, aldehyde, and carboxylic acid reactive forms.
