| Study Title | Cytotoxicity characterization in LLC-PK1 cells |
| Study Description | Nanoparticle biocompatibility was evaluated in the porcine renal proximal tubule cell line, LLC-PK1. Cytotoxicity was determined as described in the NCL protocol for LLC-PK1 Kidney Cytotoxicity Assay(GTA-1). Briefly, test materials were diluted to the desired assay concentrations in cell culture media. Cells were preincubated for 24 h prior to adding test material, reaching an approximate confluence of 80%. Cells were exposed to test material for 6, 24 and 48 h, and cytotoxicity was determined using the MTT cell viability and LDH membrane integrity assays. |
