VivoTag® 680XL – MAL is a thiol (-SH, sulfhydryl) reactive maleimide-containing near infrared (NIR) fluorochrome for molecular labeling applications. VivoTag 680XL-MAL Fluorochrome is optimized and integrated for both in vivo and in vitro applications. VivoTag 680XL-MAL’s superior brightness makes it particularly well suited for the labeling of thiol and cysteine containing molecules for a wide range of imaging applications. VivoTag 680 XL-MAL is available in 1 mg quantitiy.
|VivoTag 645||643/660||Suitable for labeling free amines (typically lysine residues)|
|VivoTag 680 XL||665/688|
|VivoTag 645 MAL||643/660||Suitable for labeling free thiols (typically cycteine residues)|
|VivoTag 680 XL MAL||665/688|
|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)|

Researchers trust our in vivo imaging solutions to give them reliable, calibrated data that reveals pathway characterization and therapeutic efficacies for a broad range of indications. Our reagents, instruments, and applications support have helped hundreds of research projects over the years. And our hard-earned expertise makes us a trusted provider of pre-clinical imaging solutions— with more than 9,000 peer reviewed articles as proof.
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.
