Variable release medium studies. Antibody release from silk lyogels as a function of variable release medium: (A) increasing levels of polysorbate 80, (B) increasing sodium chloride concentration, and (C) variable pH. Release data was truncated at approximately 85% of cumulative release observed at plateau. Lines were added as a visual aid. Antibody recovery as a function of swelling ratio for variable release medium: (D) variable polysorbate 80, (E) variable sodium chloride, and (F) variable pH compared to the model describing the recovery to swelling relationship for variable silk density.
