Application

Biotinamidoethyldisulfanyl(2-aminoethane) trifluoroacetic acid (Biotin-SS-NH2 TFA) is a cleavable, biotinylated crosslinkers. The linker can also be used for synthesis of chemical biology tools for labeling target proteins in biological experiments and assays. It possesses dual functionality: enrichment via the biotin and an embedded disulfide bridge for cleavage under reducing conditions.

Herein, we report the development of a direct discontinuous fluorometric transamidation assay for determining tissue transglutaminase (TG2) activity. In the assay reaction, TG2 catalyzes the formation of a biotin-fluorophore conjugate, using a fluorescent, high affinity gamma-glutamyl donor substrate and a
