Product Overview
The EnkiLife Fluor 700 Labeling Kit contains multiple components for labeling antibody proteins, such as high-performance fluorescent dye, purification ultrafiltration tubes, elution labeling buffer, and labeled protein storage solution. It enables easy and reliable labeling of antibodies, proteins, and other molecules for use as fluorescent probes.
Product Features
- Fast: Labeling reaction takes only about 30 minutes, balancing both labeling efficiency and effectiveness.
- Simple: Each dye reagent is pre-optimized for the corresponding antibody amount, eliminating tedious calculations. Follow the steps to achieve excellent results.
- Flexible: Dyes in large sizes kits can be aliquoted with consistent batch performance, convenient for multiple uses.
- Excellent Labeling: Optimized labeling buffer enables relatively fixed labeling sites, enhancing the homogeneity of labeled antibodies.
- Amine-Specific Labeling: The reactive group on Fluor 700 efficiently binds to primary amine groups on antibodies or other purified proteins, achieving covalent labeling.
- Protein Labeling: Primarily designed for IgG antibodies, but can also label proteins of similar size and properties to IgG.
Dye Introduction
The Fluor700 fluorescent dye is most efficiently excited by xenon arc lamps, far-red diode lasers, or lasers operating within the 675-700 nm range; it can also be effectively excited using a 633 nm He-Ne laser. Fluor700 emits in the infrared spectrum and is suitable for antibody labeling in multicolor flow cytometry applications.
