[Spin-label progesterone binding to serum albumin]. / Issledovanie sviazyvanie spin-mechenogo progesterona s syvorotochnym al'buminom.

The binding of spin label progesterone to bovine serum albumin was studied by the spin-probe technique. The binding capacity of protein was established. It was shown that protein formed a rigid complex with steroid, the correlation time of this complex being 50 ns. In the complex the radical part of the steroidal molecule has a hydrophobic environment.
