Abstract:
A new and simple procedure for purification to homogeneity of the soluble estradiol 17 beta-dehydrogenase [E C.1.1.1.62] from human placenta has been developed. The purification is achieved in a single step by affinity-absorption of Cibachrome Blue F3G-A coupled to Sepharose and selective elution with NADP+. Homogeneous estradiol 17 beta-dehydrogenase has a specific activity of 7.2 units/mg. and has been purified 2400-fold with a 93% recovery.
