Peptides are short chains of amino acids linked by peptide bonds, typically containing 2–50 amino acids. They are the building blocks of proteins and perform diverse biological functions, including signalling (hormones and neurotransmitters), immune responses (antimicrobial peptides), and regulation of physiological processes (enzyme inhibitors, receptor ligands). Synthesised naturally in cells or produced synthetically, peptides are used in biomedical research, diagnostics and therapeutics due to their specificity, relatively small size and often favourable safety profiles compared with larger proteins.

NE Peptides is joining the global effort in peptide research. We supply high-quality peptides for research use, supporting academic, preclinical and investigational studies worldwide. Our commitment includes rigorous synthesis standards, purity verification, secure packaging and reliable delivery to help researchers advance peptide science safely and reproducibly.

Benefits of peptides

• High specificity: Peptides can be designed to target specific receptors or pathways with minimal off-target effects.

• Versatility: Useful across disciplines including endocrinology, oncology, neurology, immunology and metabolic research.

• Rapid discovery and optimisation: Short development timelines and straightforward sequence modifications enable quick iteration.

• Predictable metabolism: Generally well-characterised degradation pathways and rapid clearance make dosing and pharmacokinetic studies manageable.

• Tool compounds for mechanism elucidation: Peptides serve as agonists, antagonists, modulators or delivery vehicles to probe biological systems.

• Peptide conjugation and delivery: Peptides can be conjugated to carriers, labels or stabilising moieties to expand functionality.
