Stain Name Antibody Description
HMB-45 Melanoma Associated Marker Positive results aid in the classification of melanomas and melanocytic lesions and also aid in distinguishing metastatic amelanotic melanomas from other poorly differentiated tumors of uncertain origin. The presence of the antigen indicates active melanosome formation and thus melanocytic differentiation. It is also expressed in normal fetal melanocytes, but not in normal resting adult melanocytes, regardless of the degree of pigmentation.
