Used primarily in research and diagnostic applications, this chemical is essential for studying the role of prolactin in various physiological processes. It is often employed in radioimmunoassays (RIA) to measure prolactin levels in biological samples, aiding in the diagnosis of disorders related to prolactin secretion, such as hyperprolactinemia or pituitary tumors. Additionally, it serves as a critical tool in endocrinology research to investigate prolactin's effects on lactation, reproduction, and immune function. Its iodination grade ensures high purity and suitability for sensitive laboratory techniques.
