From: Production of rumen- and gastrointestinal-resistant nanoparticles to deliver lysine to dairy cows
Cellular viability assay with L929 cells exposed to solid lipid nanoparticles (SLN) made of stearic or arachidic acids, with and without lysine (Lys), as well as free Lys, at increasing concentrations (0.125, 0.25, 0.5, 1 and 2 mg/mL of lipid). Free Lys concentrations were the same that were present in the respective Lys-loaded SLN. Values shown as mean ± standard deviation, n = 3. *Statistically different (P ≤ 0.05) from the positive controls.
