Sedimentation velocity experiments show that only monomers coexist with amyloid fibrils of human islet amyloid-polypeptide. No oligomers containing <100 monomers could be detected, suggesting that the putative toxic oligomers are much larger than those found for the Alzheimer's peptide, Abeta(1-42).
沉降速度实验表明,只有单体与人类胰岛淀粉样多肽的淀粉样纤维共存。未检测到含有少于100个单体的寡聚体,这表明假定的毒性寡聚体比在阿尔茨海默病肽β-淀粉样蛋白(1-42)中发现的那些要大得多。
