Research Overview
Leu-enkephalin
Leu-enkephalin is a standard tool in opioid receptor and pain-transmission research because it helps distinguish delta- from mu-preferring signaling. Its research value is high, but its clinical utility is limited by rapid enzymatic breakdown and delivery challenges.
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.
