for Chromeo 642 Goat anti-Rabbit IgGContents

Contents: 1 mg (Catalog No. 15044) or 0.1 mg (Catalog No. 15064) of Chromeo™ 642 conjugated Goat anti-Rabbit IgG (H+L). The antibody concentration is 2 mg/ml in 0.01 M potassium phosphate, 0.15 M sodium chloride pH 7.4, containing 2 mM sodium azide.

Specificity: This antibody was purified by immunoaffinity chromatography. It reacts with whole molecular rabbit IgG and the light chains of other rabbit immunoglobulins. No cross-reactivity with non-immunoglobulin serum proteins was observed.

Chromeo™ 642 is spectrally similar to Cy5®. The conjugated antibodies exhibit superior luminescent properties and stability towards photobleaching. The Chromeo™ 642 conjugated antibodies have absorption and emission maxima of approximately 642 and 666 nm which are compatible with common excitation sources and filter sets.

Chromeo 642 staining of etoposide-treated HeLa cells.
HeLa cells were 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 642 Goat anti-rabbit IgG.

Concurrent, multi-color staining of Phospho H2AX and tubulin using Chromeo 642 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 642 Goat anti-rabbit IgG, while tubulin was visualized using alpha Tubulin mouse mAb (Clone 5-B-1-2) and Chromeo 488 Goat anti-mouse IgG (Cat. No. 15031). The nuclei were counter-stained with DAPI, then the three separate images were merged.

for Chromeo 642 Goat anti-Rabbit IgGStorage

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.
