Neurological & Sleep Research
Short peptides that reach the central nervous system are a small and distinctive group, and most of the ones studied seriously came out of one of two traditions: Soviet-era neuropeptide research, or the mapping of endogenous sleep and opioid signalling. This category holds both lines. They are used mainly in receptor pharmacology and in sleep architecture work. Each compound is supplied with HPLC purity data for its specific batch.
