Cytotoxicity of RTDs and PG-1 for human fibroblasts. Human fibroblast (HS68) cells were exposed to 0 to 100 μg/ml of RTD-1, aRTD-1, and PG-1 in DMEM containing 0.4% FBS for 1 h at 37°C. After a 24-h recovery period, cell viability was determined by the MTT method, and viability was enumerated as the percent viability compared to the viability of incubations lacking peptide.
