FAM azide for сlick chemistry labeling. FAM remains one of the most popular fluorescent labels for various applications. Most instruments capable of fluorescence detection, ranging from plate readers to fluorescence microscopes, are able to work in the FAM channel.
With the versatility of сlick chemistry and this reagent, it is possible to attach this popular fluorophore to nearly any alkyne-bearing molecule.
FAM azide is available both as a solid compound and as a 10 mM solution in DMSO ready to use in our recommended labeling protocol. This product is a pure 5-isomer. FAM is a replacement for DyLight 488.
