Used in biomedical research as a synthetic polypeptide to study immune responses and antigen-antibody interactions. It serves as a model for understanding the behavior of more complex biological molecules. Additionally, it is employed in the development of vaccines and immunotherapies due to its ability to mimic natural antigens. In drug delivery systems, it can be utilized to create biodegradable carriers for controlled release of therapeutic agents. Its structural properties also make it suitable for use in tissue engineering scaffolds to promote cell growth and regeneration.
