General description

ColorWheel® technology is a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any ColorWheel® antibody with any ColorWheel® dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each ColorWheel® antibody and dye is lyophilized for long long-term storage, allowing for simplicity and flexibility without compromise. ColorWheel® technology requires both ColorWheel® antibody and ColorWheel® dye for Flow Cytometry application.

iFluor 647 succinimidyl ester is bright, stable far-red fluorescent dye that has spectral properties comparable to Alexa Fluor 647 and Cy dye. It exhibits an excitation max at 656 nm and an emission max at 670 nm with an extinction coefficient of 250,000 cm-1 M-1. It has stronger fluorescence and high photostability. iFluor 647 can be used for covalent labeling of antibodies and detection by flow cytometry. Its fluorescence is independent of pH from 3 to 11. It exhibits good stability, selectivity, and reactivity with protein amine groups.
We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Green Chemistry.This product is Preservative-free, lyophilized product for enhanced stability and allow for ambient shipping and thus aligns with "Waste Prevention", "Designing Safer Chemicals" and "Design for Energy Efficiency".

Physical form

CWDS-IF647-25UL Set Components

CWD-IF647-25UL - Colorwheel® Antibody-Ready iFluor 647 Dye
Lyophilized from PBS containing D-Mannitol and Sucrose, normal appearance is a dried pellet. Reconstituted solution is stable and functional as assessed by functional testing. Contains no biocide or preservatives, such as azide.

CWD-FINISH-25UL - Colorwheel® Finishing Buffer
Lyophilized from PBS. Contains no biocide or preservatives, such as azide.

Reconstitution

Reconstitute each vial by adding 25 μL PBS. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C. Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial. Reconstitute each vial by adding 25 μL of PBS. Protect from light.
