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-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.

HeLa cells stained with alpha Tubulin pAb and Chromeo 494 Goat anti-Rabbit IgG.
HeLa cells were stained with alpha Tubulin rabbit pAb and Chromeo 494 Goat anti-Rabbit IgG.

Multi-color staining of Phospho H2AX and tubulin using Chromeo 494 and Chromeo 488 secondary antibodies in untreated and etoposide-treated HeLa cells.
HeLa cells were either left untreated or treated with 100 µM etoposide for 6 hours prior to fixation with methanol. The histone-variant H2AX was stained with Histone H2AX phospho Ser139 rabbit pAb (Cat. No. 39117) and Chromeo 494 Goat anti-Rabbit IgG, while tubulin was visualized using alpha Tubulin mouse mAb (Clone 5-B-1-2, Cat. No. 39527) and Chromeo 488 Goat anti-Mouse IgG (Cat. No. 15031). The nuclei were counter-stained with DAPI, then the three separate images were merged.

Storage

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.

Guarantee

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