Abstract
1. Bradykinin, Lys-bradykinin, Met-Lys-bradykinin, des-Arg9-bradykinin and des-Arg1-bradykinin were separated by capillary zone electrophoresis in an apparatus constructed in our laboratory which utilizes a novel N2 pulsed laser-induced fluorescence detector. 2. Detection limits of 1.2 fmol for fluorescamine-derivatized bradykinin and 90 attomol for O-phthaldialdehyde-derivatized bradykinin were achieved. 3. This powerful analytical tool is described and its successful application to the measurements of bradykinin after enzymatic release from blood is documented.
