Application

A fluorogenic reagent for fluorescent N-terminal derivatization of amino acids and peptides and detection by reverse phase HPLC.
Dansyl chloride has been used:
  • as a fluorogenic reagent for fluorescent N-terminal derivatization of amino acids and peptides and detection by reverse phase high performance liquid chromatography (HPLC)[1]
  • in the derivatization of plasma samples[2][3]
  • in the quantification of immobilized alkaline phosphatase[4]

Biochem/physiol Actions

Dansyl chloride is a sulfonyl chloride compound. It is used to end tag amino groups of peptides and proteins.[5] Dansyl chloride is used for derivatization of free amino acids and amines[6] in neural samples and biological fluids.[7] It is used to study fluorescent conjugates of albumin, protein conformational changes studies and active site characterization.[7]
