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. N1205-Biotin||250 µg purified antibody, lyophilized from PBS, biotin-labeled. 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.|
Fluorescence-activated cell sorting (FACS); usually cells are fluorescently labeled with antibodies against cell-surface antigens followed by cell-sorter analysis.', $event)" style="cursor: help;">FACS: yes
Reacts with: mouse.
No signal: chicken, rabbit, Guinea pig, donkey, rat, goat, pig, horse, cow, human.
Other species not tested yet.
|Specificity||Mouse IgG (Kappa light chain), does not cross-react with rabbit, guinea pig or chicken immunoglobulins|
Unlabeled variants and several modifications of sdAbs like biotin, fluorophore or DBCO conjugation are available.
FluoTag®-X2 anti-Mouse is a species-specific FluoTag® directed against the κ light chain of mouse.
In FluoTag®-X2, two fluorophore molecules are coupled site-specifically to one individual FluoTag® molecule. Therefore, the reagent targets four fluorophores to your primary mouse antibody.
Due to the monovalent binding, there are no primary and secondary antibody clusters formed, leading to better epitope accessibility and a more precise localization. Since our FluoTags are recombinantly expressed, there is no batch-to-batch variation.
