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