吴春根 王松梅高红阳潘銮凤复旦大学上海医学院细胞与分子生物学实验室，200032摘要：目的尝试用十二烷基肌氨酸钠作为脱细胞试剂，制备脱细胞组织工程支架材料，并分析其生物学性能。

Coli. The outer membrane protein were extracted from 38 strains of avian E. coli which were isolated from the dead chickens of chicken breeding farms in 3 areas of Baoding, Qiuhuangdao and Beijing by using ultrasonic cleaving and N-Lauroyl Sarcosine Sodium, and OMP typing was done by SDS-PAGE.

方法］对分离自保定、秦皇岛和北京3个地区规模化养鸡场的病死鸡体内的38株大肠杆菌，采用超声波裂解和N-十二烷基肌胺酸钠进行外膜蛋白提取，利用SDS-PAGE进行Omp分型。

The results indicated that with this new adsorbent the efficiency of decolourisation was 85.3％and the productivity of sebacic acid was 92.0％ under the condition of 2％ of adsorbent amount used with 30min of reaction time at 90℃.

The lowest surface tension of N_xB solution was better at 25℃, and lowest surface tension would down with carbon . cmc( critical micelle concentration) and γ_ in N_(12)B are 4.1 × 10~(-4)mol/L, 24.5 mN.m~(-1),what was smaller than LAS . The cmc of N_(12)B- NaCl are down with NaCl up.The surface tension and cmc of N_(12)B and N_(16)B are higher than that of N_(12)OB and N_(16)OB because of hydrophilic group ,but that of N_(12)B is lower than that of N_(16)B because of hydrophobic group .5. The borate structure and semipolar bond were studied in different pH by infrared spectrum .It indicated that N_xB and N_xOB have not semipolar bond at pH

4、25℃，N_xB系列都有较低的表面张力，并随碳原子数的增加而最低表面张力下降。N_(12)B比同碳原子数的十二烷基苯磺酸钠的最低表面张力34.5mN／m低，且临界胶束浓度为4.1×10~(-5)mol／L，也比LAS低，且随着NaCl浓度的增加而略有下降，比较N_(12)B和N_(16)B，由于C_(16)疏水基的异构体使N_(12)B的临界胶束浓度和临界胶束浓度时的表面张力γ_(cmc都低，由于增加了亲水基团使得N_(12)OB和N_(16)OB的表面张力和临界胶束浓度都要高于N_(12)B和N_(16)B。
