for Chromeo 505 Goat anti-Rabbit IgGContents

Contents: 1 mg (Catalog No. 15040) or 0.1 mg (Catalog No. 15060) of Chromeo™ 505 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 505 can be excited in a range from 480-515 nm, which enables excitation by a green laser. Even if the emission spectrum is shifted towards longer wavelength by some nm, filters designed for fluorescein can be used with Chromeo 505 conjugated antibodies. In contrast to fluorescein, Chromeo 505 exhibits a large tolerance to a broad pH range and high photostability. Chromeo 505 conjugated antibodies have absorption and emission maxima of approximately 514 and 530 nm, which are compatible with common excitation sources and filter sets.

for Chromeo 505 Goat anti-Rabbit IgGApplication Notes

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

Chromeo 505 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 505 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.
