mEos sdAb - FluoTag-X2 - N3102-AF488-L

Single-domain antibody recognizing a photo-switchable fluorescent protein

This product was developed by

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.

Cat. No. N3102-AF488-L	200 µl purified antibody, lyophilized from PBS, fluorescence-labeled with abberior STAR 488. abberior STAR^® dyes have been especially developed for for Stimulated Emission Depletion (STED) microscopy which allows higher resolution imaging compared to confocal laser scanning microscopy. For many of the fluorescence labeled antibodies conjugated to abberior STAR^® dyes established fluorescence detection systems can be used. abberior STAR^® 635P: λ_ex 638 nm / λ_em 651 nm abberior STAR^® ORANGE: λ_ex 589 nm / λ_em 616 nm abberior STAR^® RED: λ_ex 638 nm / λ_em 655 nm This product or portions thereof is manufactured under license from abberior GmbH. abberior STAR is a trademark of abberior GmbH, Goettingen/Germany. Purchase of reagents related to the abberior STAR technology from Synaptic Systems GmbH provides a license for non-profit and in-house research use only. Any application of above mentioned technology for commercial purpose requires a separate license from abberior GmbH. 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.
Applications	ICC: 1 : 500 Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section.

Background

mEOS, is a bright monomeric green photoswitchable fluorescent protein derived from Lobophyllia hemprichii.

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.
