Alexa Fluor Products
Alexa Fluor™ fluorophore products including reactive Alexa Fluor dyes for covalent labeling and prepared Alexa Fluor conjugates of secondary antibodies, primary antibodies, and other biomolecules. Use these products for immunofluorescence assays, flow cytometry, and cellular imaging applications of all sorts. Alexa Fluor dye reagents exhibit superior brightness and photostability, outperforming conventional fluorescent reagents across the spectrum.
Our Alexa Fluor 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.
The Alexa Fluor dyes are available in several reactive forms for labeling biopolymers and derivatizing low molecular weight molecules. Most are available as an amine-reactive succinimidyl ester, and many are available in thiol, aldehyde, and carboxylic acid reactive forms.
Choose from a comprehensive selection of innovative, and time-tested labeling kits for proteins and antibodies, cDNA, RNA and DNA that feature water soluble reagents and streamlined protocols for conjugate purification. Not sure what type of protein labeling kit you need?
We offer a wide selection of Alexa Fluor dye-labeled molecules for cell structure as well as cellular and neuronal tracing including conjugates of phalloidin, dextrans, biocytins, and hydrazides.
