Results of in vitro release model fitting for proteins and lipids from SBlyo. Kinetic elaborations were performed on release data obtained from at least three independent experiments for each batch. “~” indicates that the analysis performed was “ambiguous”; therefore, the fit does not nail down the values of all the parameters, and 95% confidence bounds cannot be reported. These latter data were not considered in the interpretation of results.
