Application Note

VivoTag 645 (Protocol)

VivoTag® 645 is a red fluorescent labeling agent containing an N-hydroxysuccinimide (NHS)-ester. Labeling reagents, such as VivoTag 645 reagent, are commonly used for labeling proteins. The NHS ester moiety on VivoTag 645 reacts with amino groups to form 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 red 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.
