Figure 3From: Characterization of thimet oligopeptidase and neurolysin activities in B16F10-Nex2 tumor cells and their involvement in angiogenesis and tumor growthHPLC analysis of FRET peptides degradation by the B16F10-Nex2 supernatant. Abz-GFSPFR-EDDnp (A, C) or Abz-GFSPFRQ-EDDnp (B, D) were incubated with recombinant oligopeptidase TOP (A, B), or B16F10-Nex2 supernatant (C, D) in 50 mM Tris-HCl pH 7.4 at 37°C. Reaction products were separated by HPLC and were identified by mass spectrometry. Chromatograms developed by fluorescence detection at λem. = 420 nm and λex. = 320 nm.Back to article page
