Non-Terminal ModificationNone
Length3
Peptide/ConjuagatePeptide
Conjugate partnerNone
TechniqueCryo - TEM (Transmission Electron Microscopy), AFM (Atomic Force Microscopy), CD (Circular Dichroism spectroscopy), FTIR (Fourier Transform Infrared)
SolventSodium phosphate(0.1M, pH-11.8 and pH5.7)
MethodPeptide (4.0 mg) was added to a solution of sodium phosphate 0.1 M at pH 11.8 (buffer A, 0.3 ml), and dissolution was achieved with sonication (5 min). Gelation was triggered by subsequent addition of an equal volume of 0.1 M sodium phosphate at pH 5.7 (buffer B, 0.3 ml), resulting in a final pH of 7.4.

Solventsodium phosphate buffer
Method4.0 mg of peptide was dissolved in 300 ml of 0.1 M sodium phosphate buffer, pH 11.8 (buffer A), with the aid of sonication for 5 min, then diluted 1 : 1 with another 300 ml of 0.1 M sodium phosphate buffer, pH 5.6–5.7 (buffer B) to yield a final pH of 7.4. Samples were sonicated for another 5 min . Samples left for 24 hours for the formation of gel.
