Bac7(1-35) stability in blood fractions. (A) Western blot analysis of Bac7(1-35) incubated for different times at 37°C in 25% murine serum or plasma. Lane 1: 0.5 μg Bac7(1-35); lanes 2-6: Bac 7(1-35) after incubation with murine serum or plasma for respectively 0, 1, 4, 8, 24 hrs; lane 7: serum or plasma alone. (B) MC-LC chromatograms of Bac7(1-35) incubated at 37°C in 25% murine serum or plasma. (C) The percentages of Bac7(1-35) with respect to the t0 control were calculated following LC-MS analysis (see section Methods for further details) after incubation of the peptide with murine serum (filled squares) or plasma (filled triangles) for different times.
