In the experiment, FD-1 lyophilized collagen sponge, strain and defibrinogenase. 本实验冷冻干燥了胶原海绵、菌种及去纤酶。
CONCLUSION: Both of sintered bone and lyophilized collagen membrane are expected to be the materials for scaffolds in periodontal tissue engineering. 结论:煅烧骨和冻干胶原膜均有望成为牙周组织工程支架材料。
Methods The soluble collagen was extracted from bovine tendon and lyophilized to become a spongy hemostatic material. The constituents of collagen sponge were analyzed by SDS-PAGE electrophoresis. 方法利用酸碱法从牛腱提取精制可溶性胶原蛋白,冻干制成海绵状止血材料,用SDS-PAGE电泳分析胶原海绵的成分;
