The Science Behind Radiopeptides
At their core, radiolabeled peptides (often referred to as radiopeptides) are short chains of amino acids linked to radioactive isotopes. From my perspective, the beauty of these compounds lies in their versatility. Because peptides are essential biological building blocks, they can be precisely engineered to target specific receptors.
