H-Phe-Val-OH, also known as humanized Val-Phe-His-Leu (VHL), is a monoclonal antibody that binds to the antigen epidermal growth factor (EGF). It has been shown to have diagnostic and therapeutic properties in vitro. This antibody is used in the diagnosis of cancer tissues and is able to identify carcinoma cell lines. Furthermore, it can be used to diagnose hepatitis C virus infection. H-Phe-Val-OH blocks the binding of EGF with its receptor on the surface of cells and prevents the proliferation of cancerous cells. It also inhibits cancer growth by reducing the synthesis of proteins such as epidermal growth factor and transforming growth factor alpha.
