一般描述
CBTF (Sodium 4-((4-(cyanoethynyl)benzoyl)oxy)-2,3,5,6-tetrafluorobenzenesulfonate) is a heterobifunctional reagent. It bears a 3-arylpropionitrile (APN) group. CBTF can be prepared from 4-iodobenzoic acid. It participates in various amine-to-thiol coupling reactions. It participates in the synthesis of various antibody-dye conjugates. CBTF is widely used for antibody conjugation.
应用
CBTF is a bifunctional crosslinker for amine-to-thiol coupling. The coupling can be performed with high selectivity in biological medium using mild reaction conditions. CBTF readily reacts with organic amines in basic conditions to produce APN-probes suitable for cysteine labeling.
