Biochemical characterization of three hamster melanoma variants--I. Tyrosinase activity and melanin content
The International Journal of Biochemistry
|January 1, 1984
Abstract:
Tyrosinase activity in the soluble fraction of the cells and melanin content in the whole cells of the black-melanotic (Ma), brown-melanotic (MI) and amelanotic (Ab) hamster melanomas were studied. The activity of the soluble tyrosinase was highest in MI lower in Ma, and very low in Ab melanoma. Melanin content was greatest in the Ma, lower in MI, and none in Ab melanoma. Acrylamide gel electrophoretic pattern of the soluble tyrosinase consisted of 2 bands in Ma and MI melanomas, and of 1 band in Ab melanoma.
