Examination of tensile strength of filter paper after different treatments. Filter paper strips were treated with acetate buffer (pH 5.5), 600 µg/mL BSA (as a negative control), 8 M urea (as a positive control), or 600 µg/mL CclEXL1 for 1 h at 55 °C, and the tensile strength of each strip was measured until tearing of the strip. Standard deviations are indicated, where two asterisks (**) indicate p < 0.01 (two-tailed t test for samples treated with buffer, urea, or CclEXL1)
