Product Abs/Em (nm)  
VIVOTAG
VivoTag 645 643/660 Suitable for labeling free amines (typically lysine residues)
VivoTag 680 XL 665/688
VivoTag 800 785/810
VIVOTAG MAL
VivoTag 645 MAL 643/660 Suitable for labeling free thiols (typically cycteine residues)
VivoTag 680 XL MAL 665/688
VIVOTAG-S
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)

Application Note

VivoTag S Agents (Protocol)

N-Hydroxysuccinimide (NHS)-ester labeling reagents, such as VivoTag®-S reagents, are commonly used for labeling proteins. The NHS ester moiety reacts with amino groups at pH 7-9 to form stable amide bonds. Lysines within proteins, including antibodies, are available as targets for this chemical conjugation.,Protein labeling efficiency may vary depending upon the type of protein labeled, so different conjugation ratios may need to be attempted to attain success. For Near Infrared (NIR) fluorophore conjugation, ratios of fluorophore to protein of 4:1 have been seen to generate effective imaging agents. Not all antibodies or proteins (independent of target specificity) make good imaging agents, due to long half-lives and/or excessive accumulation in non-target sites.

White Paper

The Role of In Vivo Imaging in Drug Discovery and Development

The primary goal of preclinical imaging is to improve the odds of clinical success and reduce drug discovery and development time and costs. Advances in non-invasive in vivo imaging techniques have raised the use of animal models in drug discovery and development to a new level by enabling quick and efficient drug screening and evaluation. Read this White Paper to learn how preclinical in vivo imaging helps to ensure that smart choices are made by providing Go/No-Go decisions and de-risking drug candidates early on, significantly reducing time to the clinic and lowering costs all while maximizing biological understanding.
