Enkephalin Leucine Microspheres Suspension as a Sustained Antiplaque Antimicrobial Delivery System
The purpose of this study is to prepare a formulation containing enkephalin leucine as an antiplaque/antibacterial agent. Enkephalin leucine microspheres were prepared using a poly(D-L-lactide-co-glycolide) (PLGA) as a delivery system.

MALDI-induced fragmentation of leucine enkephalin, nitro-Tyr-leucine enkaphalin, and d5-Phe-nitro-Tyr-leucine enkephalin [PDF]
The long-term objective of this study is to use MALDI MS and MS/MS to study the fragmentation pattern of in vitro nitrotyrosine-containing peptides in order to assist the interpretation of MS-identification of endogenous nitroproteins in human tissues and fluids.

Leucine enkephalin—A mass spectrometry standard
AbstractThe present article reviews the mass spectrometric fragmentation processes and fragmentation energetics of leucine enkephalin, a commonly used peptide, which has been studied in detail and has often been used as a standard or reference compound to test novel instrumentation, new methodologies, or to tune instruments.

THE DISTRIBUTION OF METHIONINE‐ENKEPHALIN AND LEUCINE‐ENKEPHALIN IN THE BRAIN AND PERIPHERAL TISSUES [PDF]
A method is described for the rapid extraction of opioid peptides from the brain and other tissues. The method is based on acid extraction of tissues followed by adsorption of the extract onto Amberlite XAD‐2 resin. Elution with methanol separates the enkephalins and α‐endorphin from β‐endorphin.Over 90% of the opioid peptide activity isolated from ...

Light microscopic immunocytochemical identification of leucine enkephalin
Leucine-enkephalin is a potent and naturally-occurring opioid peptide which serves to inhibit other neurotransmitters involved with pain perception, thereby reducing its emotional and physical impact. Nevertheless, there is little data in the literature concerning leucine-enkephalin-immunoreactivity (Leu-enk-ir) in the human claustrum.
