From: Cytochrome P450 aromatase expression in human seminoma
Immunoblot of aromatase from seminoma extracts. Lane 1: purified P450 arom protein from human placenta (positive control). Lane 2: negative control prepared as described in Material and Methods. Lanes 3, 4, 5: 55 kDa P450 arom immunoreactive bands from lysates of three different seminoma extracts. Numbers on the left correspond to molecular weights of marker proteins.
