anti-Mouse IgG1 sdAb - FluoTag-X2 - N2002-At488-S

Secondary single domain antibody specific for mouse IgG1


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.

Camelid single domain antibody

Cat. No.: N2002-At488-S
Amount: 500 µl
Price: $220.00
Cat. No. N2002-At488-S 500 µl purified antibody, lyophilized from PBS, fluorescence-labeled with ATTO® 488

For many of the fluorescence labeled antibodies conjugated to ATTO® dyes from ATTO-TEC the established CyDye fluorescence detection systems can be used.
ATTO® 550 has similar exitation and emission properties as Cy3, and ATTO® 647N as Cy5.
ATTO®647N and ATTO®594 dyes are suitable for Stimulated Emission Depletion (STED) microscopy which allows higher resolution imaging compared to confocal laser scanning microscopy.
ATTO®594 is also recommended for PALM and dSTORM high resolution microscopy.

ATTO is a trademarks of ATTO-TEC GmbH, Siegen/Germany.

FluoTag®-X2 anti-Mouse is a species-specific FluoTag® directed against the IgG1 subtype from Mouse. In FluoTag-X2, two fluorophore molecules are site-specifically coupled to one individual FluoTag molecule. The reagent therefore 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.
