SSEA-1-PrNH2 is primarily used in biomedical research and applications, particularly in the study of stem cells and cellular differentiation. It serves as a specific marker for identifying and isolating certain types of stem cells, such as embryonic stem cells and germ cells, due to its ability to bind to specific surface antigens. This compound is also utilized in the development of targeted therapies and diagnostics, where its selective binding properties enable the precise delivery of therapeutic agents or imaging probes to specific cell populations. Additionally, SSEA-1-PrNH2 plays a role in understanding cell surface interactions and signaling pathways, contributing to advancements in regenerative medicine and cancer research.
