本工作采用 体外 重构方法研究动粒肌肽凝胶在受控条件下的多孔弹性。量化了肌动球蛋白凝胶和包埋溶剂的动力学,通过这些动力学证明了网络多孔弹性。我们还讨论了实验挑战,常见陷阱以及与细胞骨架力学的相关性。
我们已经开发了一种体外方法来表征多孔弹性肌动肌肽凝胶的力学,作为细胞骨架的模型系统,更一般地说,细胞质已被证明表现为多孔弹性活性材料。该方法提供了肌球蛋白收缩性如何促进流体流动的出现以及网络和细胞质速度如何在时间和空间上相关的见解。这种简单的方法使我们能够提取动态演变系统的机械性能,而无需使用任何无法使用AFIM等传统工具的复杂设备或技术。
该方法可以深入了解多孔弹性活性材料的流变学,而不管活性凝胶和包埋流体的特异性如何。首先,将 10 到 12 个 1.5 号玻璃盖玻片放入自制的聚四氟乙烯支架中,并在 400 毫升烧杯中制备食人鱼溶液。在化学罩中的冰上制备溶液。
