Contents: 250 µl (Catalog No. 15072) or 35 µl (Catalog No. 15073) of affinity purified goat anti-rabbit IgG (H+L) conjugated to ATTO 532 (GSD) in PBS, pH 7.4, 0.01% sodium azide.

Specificity: This antibody was purified by immunoaffinity chromatography and cross-adsorbed. It reacts with whole molecule rabbit IgG and shows minimum cross-reactivity with bovine, chicken, goat, guinea pig, horse, human, mouse, rat and sheep serum proteins. No cross-reactivity was observed with non-immunoglobulin serum proteins.

ATTO 532 (GSD) belongs to a class of fluorescent labels for the orange-red spectral region, like Rhodamine 6G. The dye is very photostable, exhibits a strong absorption and an excellent fluorescence quantum yield. ATTO 532 (GSD) is very soluble in water, allowing conjugations with high dye-to-protein ratios.

Application Notes

Immunofluorescence: 1:1,000 to 1:2,000

ATTO 532 (GSD) Goat anti-Rabbit IgG is recommended by Leica Microsystems for Super-Resolution Fluorescence Microscopy using the Leica SR GSD microscope for performing Ground State Depletion with Individual Molecule return (GSDIM) microscopy. GSDIM can mathematically re-construct images with resolution as low as 20 nm.

Tubulin was stained with a primary polyclonal rabbit antibody and with ATTO 532 (GSD) Goat anti-Rabbit IgG, then imaged using widefield (left) and GSDIM (right) microscopes. GSDIM provides much sharper resolution. These images are courtesy of Leica Microsystems, Germany.


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
