Camelid single domain antibodies (sdAbs) consist only of one antigen binding site of an Alpaca heavy chain antibody. With only ~15 kDa, these Tags are about 10-times smaller than conventional IgG antibody molecules.

200 µl purified antibody, lyophilized from PBS, fluorescence-labeled with
AZdye 568.
Albumin was added for stabilization. For reconstitution refer to the NanoTag reconstitution and storage instructions. Reconstitute immediately upon receipt! Avoid bright light when working with the antibody to minimize photo bleeching of the fluorescent dye. |

mScarlet-i is a basic, very bright red fluorescent protein, derived from a synthetic construct (1). It is reported to be a rapidly-maturing, constitutively fluorescent monomer with moderate acid sensitivity. It is a useful acceptor in Foerster resonance energy transfer (FRET) based imaging techniques (2).
Unlabeled variants and several modifications of sdAbs like biotin, fluorophore or DBCO conjugation are available.
In FluoTag®-X2 two fluorophore molecules are site-specifically coupled to each FluoTag molecule. Therefore, the reagent simultaneously targets two fluorophores to the protein of interest, which ensures up to two-fold („2X“)-brighter signals. Owing to the small size of the FluoTags, the distance between the target epitope and each fluorophore is ~ 3 nm.
In comparison to detection systems using conventional antibodies, FluoTag-X can thus improve the localization accuracy by 10-15 nm. Both features - superior brightness and precise fluorophore placement - render the FluoTag-X products excellent tools for all microscopy techniques.
