Abstract
A visualization kit includes (i) a cyanoacrylate and (ii) a fluorescent agent containing at least one tetrazine of formula 1:wherein X and Y represent independently a nonionic, electron-withdrawing group selected from halogens, azide, cyano and O-A-R, in which A represents a single bond or a C1-C4 alkyldiyl and R is alkyl, alkenyl, alkynyl, cycloalkyl or epoxyalkyl, or an aziridine group, which is optionally substituted by alkyl or aryl. A method of cofugation and a method of visualizing traces on a substrate utilizing these components are also presented.
