Contents: 250 µl (Catalog No. 15049) or 35 µl (Catalog No. 15069) of affinity purified goat anti-rabbit IgG (H+L) conjugated to ATTO 655 (STED) 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.

Characteristic features of the ATTO 655 (STED) are strong absorption, good fluorescence quantum yield, excellent thermal and photo stability, outstanding ozone resistance, very good water solubility, and very little triplet formation.

Application Notes

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

ATTO 655 (STED) Goat anti-Rabbit IgG is recommended by Leica Microsystems for Super-Resolution Fluorescence Microscopy using Leica's STimulated Emission Depletion (STED) microscopes. STED enables resolution of 50-70 nm.

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.
