Beschreibung

Allgemeine Beschreibung

CF^™ 750 succinimidyl ester (CF750 SE) is used for labeling proteins or other biomolecules having an amine group. The succinimidyl ester group of the dye reacts with an amine group to form a stable amide linkage.

Near-IR CF dyes are a group of fluorescent dyes with absorption and emission wavelengths between 650 and 800 nm. Near-IR CF dyes are significantly brighter and more stable than any other commercial dye of similar wavelengths. Near-IR CF dyes offer important advantages over traditional visible light dyes. Because cellular or tissue components produce minimal autofluorescence in the near-IR region, near-IR dyes have the potential to offer highly specific and sensitive detection in complex biological systems. Also, because light with wavelength in the near-IR region has strong tissue penetration, near-IR dyes are ideal for in vivo fluorescence imaging, an emerging field that has advanced rapidly in recent years. Futhermore, near-IR dyes are also excellent dyes for in- or on-cell and membrane-based Western assays. CF750 is so bright, it can be excited at 633 nm, but still emits stronger fluorescence at ~770 nm than APC-based tandem dyes, making the dye particularly useful for flow cytometry applications without the spillover and stability challenges encountered with tandem dyes.

Anwendung

CF^™ 750 succinimidyl ester is suitable for labelling antibodies during for xenograft Imaging of CD25-positive tumors. It may also be used for labelling proteins to track the protein delivery in nasal mucosa using nanoparticles containing an anionic lipid in their core (NPL).

Leistungsmerkmale und Vorteile

1. Near-IR CF dyes are exceptionally bright and stable. 2. Water-soluble. 3. Ideal for in vivo image. 4. Less immunogenic than other competitive dyes.
