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.

250 µg purified antibody, lyophilized from PBS. For reconstitution add 250 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use. Antibodies should be stored at +4°C when still lyophilized. Do not freeze! |
| Applications |
|
| Clone | 1F8 |
| Immunogen | Recombinant protein corresponding to AA 1 to 227 from Entacmaea quadricolor mRuby |
| Specificity | Recognizes most common mRuby derivatives |
| Remarks |
This single domain antibody carries a C-terminal cystein available for conjugation. |
|

mRuby and mRuby derivatives are bright monomeric red fluorescent proteins derived from Entacmaea quadricolar. They show exceptional resistance to denaturation at pH extremes.
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.
