I'm working with B16F10cell line... But I have some problem with melanin production. Now (3 passages after thawing) cells are transparent and melanin is only in the medium.. do You know which should be the reason?

If you recently bought the cells and use complete DMEM to grow them, you should not have trouble with pigmentation.... Alot of suggestions has been given regarding your current situation. You can read here:
