N-Terminal ModificationNapthalene
C-Terminal ModificationOlsalazine
Non-Terminal ModificationNone

Peptide/ConjuagateConjugate
Conjugate partnerOlsalazine
TechniqueTransmission Electron Microscopy (TEM)
SolventWater
Method6.0 mg of peptide dissolved in 0.50 mL of water to give a clear solution, after which a change in pH to 5.0 resulted in a viscous suspension. Ultrasound sonication of the suspension for 2 min or an increase of its temperature to ∼60 °C followed by cooling to ambient temperature afforded a transparent, yellow gel.

Conjugate partnerNone
TechniqueCryo - Transmission Electron Microscopy (TEM)
SolventPBS (Phosphate Buffer Saline)
Method1.0 mg of each peptide and equal molar of sodium carbonate to the peptide were first suspended in PBS buffer (pH = 7.4); the sodium carbonate was used to neutralize the terminal carboxylic acid of peptides. The suspensions were then heated to 80°C to form clear solutions. The gels would form after cooling back to room temperature within 3 min.
