Activated NHS-ester of AMCA (aminomethyl coumarin acetate) dye. This NHS ester is an amine-reactive dye for labeling of amine groups in proteins, peptides, amino-modified oligos, and other target molecules.
AMCA is one of the brightest blue fluorescent dyes. This fluorophore has a relatively large Stoke’s shift, high resistance to photobleaching, and pH-independent fluorescence from pH 4 to 10. AMCA is a widely used fluorophore for multiple-color labeling due to its minimal fluorescence overlap with green- and longer wavelength-emitting fluorescent dyes.

AmdU (5-Azidomethyl-2'-deoxyuridine)
Azidomethyldeoxyuridine (AmdU) is an azide-contained nucleoside that is incorporated into nascent DNA by cellular polymerases. The azide groups attached to DNA this way can be subsequently modified with alkynes or cycloalkynes via copper-catalyzed or strain-promoted click reaction.AMCA azide
