Abstract
The general effects of solubility and hydrophobicity-hydrophilicity on the immunogenicity of synthetic and natural polymers are presented. The degree of hydrophobicity or hydrophilicity was determined from contact angle measurements. The surface tension components, obtained from the contact angles, were then correlated with the degree of immunogenicity for each substance. The results indicate that highly hydrophobic and highly hydrophilic polymers are not immunogenic. Moderate hydrophobicity as well as moderate hydrophilicity, and solubility in water favor immunogenicity (provided the molecular mass be at least 10,000 Da). For example, the solubilization of zein (a hydrophobic insoluble maize protein) prior to immunization causes zein to become immunogenic.Keywords
