for Chromeo 488 Goat anti-Rabbit IgGContents

Contents: 1 mg (Catalog No. 15041) or 0.1 mg (Catalog No. 15061) of Chromeo™ 488 conjugated Goat anti-Rabbit IgG (H+L) and 1 ml MAXfluor™ Mounting Medium. 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 488 is spectrally similar to FITC and Alexa® 488. The conjugated antibodies exhibit superior luminescent properties. Chromeo 488 conjugated antibodies have absorption and emission maxima of approximately 490 and 527 nm, which are compatible with common excitation sources and filter sets.

Immunofluorescence: 1:1,000 to 1:2,000 dilution
Plate-based assays: 1:800 to 1:1,000 dilution

Chromeo 488 Goat anti-Rabbit IgG is recommended by Leica Microsystems for Super-Resolution Fluorescence Microscopy using Leica's STimulated Emission Depletion (STED) microscopes. It has also been tested and verified by Leica for use in Ground State Depletion with Individual Molecule return (GSDIM) using the SR GSD microscope. STED enables resolution of 50-70 nm, while GSDIM can mathematically re-construct images with resolution as low as 20 nm.

for Chromeo 488 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, and the MAXfluor Mounting Medium, 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.
