MART-1 (26-35) (human) is primarily used in immunological research and cancer studies. It serves as a peptide antigen in the development of cancer vaccines, particularly for melanoma. Researchers utilize it to stimulate T-cell responses, aiding in the study of immune system interactions with cancer cells. Additionally, it is employed in the design of adoptive T-cell therapies, where it helps in targeting and destroying melanoma cells. The peptide is also used in diagnostic assays to evaluate immune responses in patients undergoing immunotherapy. Its role in understanding tumor immunology makes it a valuable tool in advancing cancer treatment strategies.
