Peptide synthesis is a crucial technology that enables the creation of custom peptides for applications in biomedical research, drug discovery, and diagnostics. Among the available synthetic strategies, solid-phase peptide synthesis (SPPS) and liquid-phase peptide synthesis (LPPS) are the two dominant approaches. Understanding their differences is essential when planning a synthesis strategy tailored to your research or production goals. 

Peptides—short chains of amino acids—play essential roles in biological functions and have become indispensable tools in research, diagnostics, and drug development. But how are these small yet powerful molecules made in the lab? That’s where peptide synthesis comes in.
