Description

General description

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.

Features and Benefits

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.

Preparation Note

Protect from light and moisture

Reconstitution

Dissolve in DMSO
