Label antibodies, small molecules, proteins, or peptides with VivoTag® NIR fluorescent dyes.
Available as either NHS esters or maleimide reactive dyes, making conjugation to either free amine (-NH3) or free thiol (-SH) containing molecules possible, our VivoTag fluorescent dyes have been validated for in vivo and in vitro applications. Please refer to the configuration table below to see which VivoTag fluorescent agent is best for your research studies.
VivoTag is available in multiple sizes and wavelengths to fit your imaging needs.

VivoTag-S 750-MAL is a thiol (-SH, sulfhydryl) thiol-reactive near-infrared fluorochrome for labeling free cysteines or thiol groups on small molecules via maleimide chemistry. Available in 5 mg quantity its superior brightness makes it particularly well suited for the labeling of thiol and cysteine containing molecules for a wide range of imaging applications. It is optimized for use with IVIS® fluorescence tomography imaging systems with expanded wavelength capabilities to enable quantitative imaging of up to four channels and four different biomarkers of interest in vivo.

| VivoTag 680-S | 665/688 | "S" for self-quenching. When a protein is labeled with multple VivoTag-S molecules, there is a shift in the absorbance of the dye, which will reduce the signal. Only choose 'S' form if your labeling ratio of dye:protien will be 1:1. If multiple dyes are to be conjucated onto your protein, the non-"S" version should be used. Suitable for labeling free amines (typically lysine residues) |
