中文摘要:

似人类的骨胶原(HLC ) 的自我相互作用上的温度的效果被恐水病的相互作用调查层析, calorimetric 测量,和钠 dodecyl sulphate-polyacrylamide 胶化电气泳动(SDS 页) 分析。结果证明相互作用角色的三种类型可以在 350 点在 HLC 分子之间存在

英文摘要:

Effects of temperature on self-interaction of human-like collagen (HLC) were investigated by hydrophobic in- teraction chromatography, calorimetric measurement, and sodium dodecyl sulphate-polyacrylamide gel electropho- resis (SDS-PAGE) analysis. Results show that three types of interaction roles may exist between ttLC molecules at 3--50 ℃, which were divided into three narrower temperature ranges. In temperature range from 3--22 ℃, hy- drogen bonding plays a key role in the formation of a gelatinous aggregate. In the range of 22--38 ℃, hydrophobic bonds accompanied by hydrogen bonds are involved in the formation compact aggregates. When temperature is above 38 ℃ the hydrophobic effect formed in the HLC monomer results in the loss of its ability to self-interact.
