Photoaffinity radiolabeling techniques have been widely used to characterize the properties of peptide hormone receptors. However, the identity of authentic receptors is often uncertain because many macromolecules are labeled. These ambiguities are due, in part, to the use of a heterogeneous mixture of photoreactive photoligands, many of which have no or low affinity for the relevant hormone receptor. In this report, we describe the synthesis, purification, and structural analysis of the… CONTINUE READING
