Effect of aging time and surface properties on the hydrophobicity and functionality of immunoglobulin M (IgM) antibody adsorbed on cellulosic films. Red, cellulose acetate film (CAF); blue, regenerated cellulose film (RCF). (A) Effect of IgM antibody aging on the relative size of agglutinates on CAF and RCF. Data were fitted with a one-phase decay model, with R2 of 0.9967 (CAF) and 0.9993 (RCF). (B) Surface hydrophobicity (contact angle) with respect to aging time. Data were fitted with Boltzmann function, with R2 of 0.999 (CAF) and 0.996 (RCF).
