Research Overview
Met-enkephalin
Met-enkephalin has been extensively used in receptor pharmacology and nociception studies to map mu and delta opioid biology. The main limitation in translational work is very short half-life from peptidase cleavage and poor systemic stability.
Statherin
Statherin has been extensively studied as a key regulator of enamel mineral equilibrium and pellicle biology. It is used in biomimetic dentistry research to model or improve enamel protection and remineralization.
