Prostaglandin E binding by plasmatic membranes of thyroid gland cells

: The binding of prostaglandins E (PGE) with human and bovine thyrocyte plasmatic membranes was investigated by the new method with material from the kit for radioimmunoassay of PGE. There was a high affinity and a low affinity site for the specific PGE binding on human and bovine thyrocytes plasmic membranes. The effect of thyrotropin and cyclic nucleotides on the PGE binding by the membranes was revealed.
