| Outline of Final Research Achievements |
In this study, we have investigated the intermolecular interactions of fibrinogen molecules in the process of the cryogelation. The additive effects of urea and NaCl on the cryogelation were examined to elucidate the roles of hydrogen bonding and electrostatic interaction. The cryogelation were inhibited by the addition of urea and NaCl. The analysis of the experimental data suggested that the protofibrils were mainly formed by hydrogen bonding and the lateral aggregation of protofibrils was mainly regulated by electro static interaction. Furthermore, fibrinogen degradation products (FDPs) were made by plasmin to predict the interaction sites. Fragment X which is a FDP with loss of alpha C-chains could not form the cryogel, and therefore alpha C-chains are essential for the cryogelation.
