Application

Abz-LFK(Dnp)-OH trifluoroacetate (TFA) salt is an Angiotensin Converting Enzyme (ACE) fluorescent peptide substrate that binds specifically to the C domain of ACE. Abz-LFK(Dnp)-OH TFA has been used to study the development of new antibacterial calixarene derivatives, as well as the efficacy and toxicity of the antimicrobial peptide M33 as a possible antimicrobial agent in lung infections and sepsis.

Biochem/physiol Actions

Abz-LFK(Dnp)-OH is an Angiotensin Converting Enzyme (ACE) fluorescent peptide substrate specific for the C domain for real time fluorescent assay (ACE, Peptidyl Dipeptidase, Kininase II, E.C. 3.4.15.1).
