Physicochemical characteristics of proteins adsorbed specifically to amine or unmodified particles. The proteins bound to amine or polystyrene particles are similar in terms of chain length (length) and pI; however, proteins bound to amine are more hydrophobic than proteins bound to unmodified particles (Student's t-test p = 0.0224) as shown by their grand average hydropathicity (GRAVY). Box plots show the median value and interquartile range (IQR). Whiskers indicate outliers as 1.5×IQR.
