Figure 5: Permeation of human insulin across TR146 buccal cell layers in the presence of increasing aspartic acid concentrations.

From: Pre-formulation and systematic evaluation of amino acid assisted permeability of insulin across in vitro buccal cell layers

Figure 5

(a) Percentage of insulin permeated in the presence of various concentrations of aspartic acid. (b) Comparing the percent enhancement of insulin permeability through TR146 cell layers in the presence of various concentrations of arginine and solution pH. (c) Comparing the solubility at 25 °C and permeability of insulin through TR146 cells layers, of insulin in the presence of various concentrations of aspartic acid.
