What is hmb 45?

HMB-45 is a monoclonal antibody that is typically used as a diagnostic marker for melanoma. It specifically binds to a protein called Melan-A, which is found in normal melanocytes (the cells that produce melanin) as well as melanoma cells. In addition to its diagnostic role, HMB-45 has also been studied for its potential therapeutic applications in melanoma treatment. However, further research is needed to fully understand its effectiveness in this context.
