To ensure a maximum in photostability of Chromeo 494 conjugates under all experimental conditions, we recommend the use of Mowiol or TDE as mounting medium. Vectashield or MAXfluor Mounting medium might negatively influence the photostability of Chromeo 494.

Chromeo 494 Goat anti-Mouse 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.

HeLa cells were stained with alpha Tubulin mouse monoclonal antibody (Clone 5-B-1-2, Cat. No. 39527) and Chromeo 494 Goat anti-Mouse IgG. Histone H3 was stained with Histone H3 trimethyl Lys4 rabbit polyclonal antibody (Cat. No. 39159) and the ATTO 647N (STED/GSD) Goat anti-Rabbit IgG (Cat. No. 15048) secondary antibody.

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.


This product is guaranteed for 6 months from date of receipt.
