Background:

• Elastin-like peptides (ELPs) are synthetic polymers with unique thermoresponsive properties.
• Their reversible self-assembly makes them attractive for various biocompatible applications.
• Efficient and scalable production of ELPs remains a significant challenge in the field.

Purpose of the Study:

• To develop a practical and effective method for synthesizing thermoresponsive elastin-like peptides (ELPs).
• To demonstrate the temperature-dependent self-assembly of synthesized ELPs.

Main Methods:

• Utilized liquid-phase peptide synthesis (LPPS) for ELP production.
• Employed a hydrophobic benzyl alcohol support (HBA-Tag) for enhanced synthesis.
• Incorporated fragment condensation strategy for efficient peptide assembly.

Main Results:

• Successfully synthesized short ELPs with high purity and yield.
• Demonstrated clear temperature-dependent reversible self-assembly of the synthesized ELPs.
• The HBA-Tag and fragment condensation approach proved effective for ELP synthesis.

Conclusions:

• The described LPPS method with HBA-Tag and fragment condensation is a viable strategy for producing thermoresponsive ELPs.
• This approach facilitates the controlled synthesis of ELPs with predictable self-assembly behavior.
• The findings contribute to overcoming challenges in ELP supply and enable broader applications.
