| FH Moritz (Verified Customer) (09-12-2024) | In HEK293T cells transfected with SFFV::POI-TurboID-SPOT fusion construct, incubated with SPOT atto 488 label (1:1000) the background was very high and no specific signal from SPOT could be observed. Another antibody used as control gave a clear signal of the fusion protein. Applications: Immunofluorescence Cell Tissue Type: HEK293T cells |
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
