  • Left: HeLa cells transiently expressing pSpot Spot-Tag?-Actin (ev-31) were immunostained with Spot-Label? Alexa Fluor? 568 (red, ebAF568, 1:800) and DAPI (blue). Right: Control staining with Spot-Label? Alexa Fluor? 568 (red, ebAF568, 1:800) and DAPI (blue) of untransfected HeLa cells showing no unspecific background. Scale bar, 10 μm. Images were acquired with the Thermo Scientific CellInsight CX7, 20X objective.

Product Information

anti-Spot-Tag VHH/ Nanobody conjugated to fluorescent dye for immunofluorescence, microscopy, and immunoblotting of Spot-tagged proteins

DescriptionImmunofluorescence of Spot-tagged proteins with anti-Spot Nanobody conjugated to fluorescent dye. Spot-Label is much smaller compared to conventional primary plus secondary IgG antibodies (IgG complex). Due to its small size, Spot-Label is optimal for effective labeling with minimal fluorophore displacement for super-resolution microscopy.

• Capture and detection tag without compromises in applications

• Higher image resolution

• Superior accessibility and labelling of epitopes in crowded cellular/organelle environments

• Strong avidity effect from bivalent form of Spot-VHH

• Fulfills highest requirements on antibody validation: structure and function characterized
