What is the viscosity and melting point of Biosilk?

When Biosilk or Biosilk 521 is in liquid form, the viscosity is similar to PBS buffer (only 0.3wt% protein).

When the Biosilk products are foamed into a 3D network, it is not possible to measure viscosity, as Biosilk is a porous scaffold, not a gel. However, the stiffness may give an indication of the behavior:  Biosilk with integrated mesenchymal stem cells have a Youngs modulus 1.8 +/−0.5 MPa with 25% elongation. For the same reason, Biosilk does not have a gelation temperature. Biosilk starts to unfold at a temperature of 47°C.
