XenoLight Fluorescent Dyes/Kits

For improved fluorescence results, Caliper offers Near Infrared dyes in 3 wavelengths ideal for in vivo imaging. Caliper’s XenoLight CF Rapid Antibody Labeling kits are designed for preparing fluorescently labeled antibodies for in vivo imaging in small animals. Each kit contains one of our superior near-IR XenoLight CF dyes and everything else you need for carrying out the labeling reaction and purifying the labeled product. The reactive dye has a succinimidyl ester group, which reacts with an amine group of the protein (i.e., lysine side-chain amine) to form a stable amide linkage. The dye is supplied in three separate vials, each containing sufficient dye for labeling 1-2 mg of IgG antibody. Following the labeling reaction, unconjugated dye is conveniently and rapidly removed by ultrafiltration using the provided NanoSep membrane filtration vials.

XenoLight CF dyes are also available in non-kit packaging. These dyes are available in 1mmole quantity, which is enough to label 5 mg of an IgG antibody. XenoLight DiR is a lipophilic, near-infrared fluorescent cyanine dye useful for staining the cytoplasmic membrane.
