Atto-conjugated anti-Drosophila primary antibodies are affinity-purified monoclonal or polyclonal antibodies directed against Drosophila melanogaster proteins or immunoglobulins and directly labeled with highly photostable Atto fluorophores. These synthetic dyes provide excellent brightness, defined excitation/emission spectra, and exceptional resistance to photobleaching, making them ideal for advanced fluorescence imaging and flow cytometry. Direct labeling eliminates secondary antibodies, reducing background while improving staining consistency and experimental efficiency.
Key Features
- Superior photostability: Atto dyes withstand prolonged illumination and high-power laser imaging, including STED microscopy.
- Broad spectral range: Available in multiple fluorophores for flexible multicolor fluorescence experiments.
- Optimized labeling: Controlled dye-to-protein ratios preserve antibody affinity while delivering intense fluorescence signals.
- Validated formats: Monoclonal and polyclonal antibodies supplied in liquid, lyophilized, or azide-free formulations for diverse applications.
Applications
These antibodies are widely used for confocal, STED, TIRF, and single-molecule imaging, multicolor immunofluorescence, RNA FISH co-staining, and flow cytometry. Their stable fluorescence and consistent epitope recognition support high-resolution visualization of Drosophila tissues, embryos, and cultured cells across conventional and super-resolution microscopy workflows.
