[Met5]-Enkephalin, Amide TFA（Cat No.:I046147）is a synthetic pentapeptide belonging to the endogenous opioid peptide family, functioning as a neuromodulator and neurotransmitter. This amidated analog of methionine-enkephalin binds primarily to δ- and μ-opioid receptors, regulating pain perception, stress response, and neuroendocrine functions. The amidation enhances stability and receptor interaction, while the TFA salt form improves solubility and handling in laboratory settings. [Met5]-Enkephalin, Amide TFA is widely used in neuroscience, pharmacology, and pain research, providing a valuable tool to study opioid receptor signaling and peptide-based therapeutic strategies.
