FluoTag®-X2 anti-mScarlet is derived from an in-house developed single-domain antibody (sdAb) recognizing mScarlet-i with high affinity and specificity. Our FluoTag-X2 series features two site-specifically coupled fluorophores per molecule. The reagent can therefore simultaneously target two fluorophores to your protein of interest, which results in enhanced image brightness. Owing to the small size of our FluoTags, the distance between the target epitope and each fluorophore is below 4 nm. In comparison to conventional detection systems using conventional antibodies, our FluoTag-X2 series can thus improve the localization accuracy by 10-15 nm. Both features – enhanced brightness and precise fluorophore placement – render our FluoTag-X2 products superior tools for all microscopy techniques.


Specificity: Recognizes mScarlet-i and most common derived red fluorescent proteins like mRFP and mCherry in their native conformation. It does not cross-react with GFP or mTagBFP derivatives. For more detailed information see the Product Reactivity Chart.

Concentration: 2.5 µM protein, 5 µM fluorophore
