Fabrication of Recombinant Spider Eggcase Silk Protein in Different Morphologies Under The Lubricant-Based System
Spider eggcase silk as a task-specific fiber draws increasing attention due to its unique behaviors. A silk protein
from the tubuliform spidroin 1 is genetically engineered and assembled with various morphologies in different lubricant
systems. The underling mechanism for the assembly ofsilk proteins was studied with regard to the surface tension, viscosity
and temperature.The phase separation of silk proteins is significantly affected by the interfacial diffusion behaviors and the
evaporation of HFIP.
