Fig 3. Pegylated versions of PA inhibit complement activity in a hemolytic assay.

Fig 3

(A) Hemolytic assays using factor B-depleted serum were performed with PA dissolved in DMSO and its pegylated derivatives dissolved in water. Factor B-depleted serum was incubated with 0.77mM of each peptide and then added to sensitized sheep erythrocytes. (B) Titration of increasing amounts of PA and PA-dPEG24 in the hemolytic assay. Water and DMSO were used as vehicle controls in the presence of factor B-depleted serum. GVBS++ is a buffer- only control. Values are the means of three independent experiments. Error bars represent the SEM.
