Tyrosinase, technical only
Use
Tyrosinase is an enzyme involved in the production of melanin, expressed in melanocytes, and serves as a key marker in the diagnosis of melanocytic tumors. In pathology, tyrosinase is used to confirm the diagnosis of melanoma, distinguishing it from other skin cancers and non-melanocytic tumors. Its expression is also utilized to monitor melanoma progression and metastasis.
