SCL protein sampling in vitro. A Total protein of Nesofilcon A, Balafilcon A, Etafilcon A, and Senofilcon A lenses after soaking for 1 h in HTPM, then sonicated for 10 min in PBS, 10% acetone, and 4M guanidine, B Total protein from Etafilcon A lenses soaked in HTPM for 5 min, 1 h, 4 h, and 16 h, C Total protein by SCL power (− 0.75DS, − 8.00DS, and + 2.00DS) after a 1 h incubation in HTPM. Error bars represent standard deviation, n = 3 for all experiments. NS not significant
