Investigate the Effect of Thawing Process on the Self-Assembly of Silk Protein for Tissue Applications

Figure 5

Demonstration of the self-assembly process of silk protein; the prepared 3.6% silk solution was frozen at −80°C for 1, 2, 3, 4, 5, 6, and 7 days before applying the −80ST48 process and recorded by a light microscope every 24 hours, at ×40, ×200, and ×400 magnifications.
