PeptideSyn^TM Peptide Synthesis Technology

Microwave Synthesis: Advancing Efficiency and Precision

Microwave synthesis, a revolutionary method employed by LifeTein, facilitates rapid and straightforward peptide synthesis. This technique harnesses the power of microwaves to instantly heat solvents or amino acids in solution through dipolar rotation or ionic conduction. The result is a more efficient, precise, and safer mode of heating, particularly beneficial for synthesizing peptides.

LifeTein has successfully utilized our proprietary technology to produce peptides exceeding 100 amino acids, with our longest peptide to date measuring an impressive 169 amino acids.

Catalytic active sites and most receptor binding sites for small ligands are found at domain and subunit interfaces. Long peptides are frequently synthesized to study the protein-receptor binding. Two active sites are indicated by the presence of the bound ligands (yellow). Both sites are at an interface between the two subunits of the protein.

Conventional Solid-Phase Peptide Synthesis (SPPS) typically involves long coupling times, extended deprotection periods, multiple washing steps, and Kaiser tests for acylation confirmation. This time-consuming process becomes especially challenging when synthesizing complex peptides, such as beta-amyloid or large enzymes, where on-resin aggregation can occur. LifeTein addresses these challenges with a platform designed for rapid assembly of multiple peptide fragments using native chemical ligation and the heating method of microwave technology.

LifeTein's PeptideSyn technology offers a practical platform for synthesizing long peptides for research and pharmaceutical purposes. This technology has been employed for in-house testing of various biologically active peptides and enzymes, including those containing D-amino acids or pseudoproline dipeptides. The flexibility of PeptideSyn technology allows the selection of efficient coupling reagents, such as HBTU, HATU, HCTU, ByBroP, BOP, PyBOP, and TBTU, ensuring rapid SPPS.

Case Study: Efficient Synthesis of Amylin and Beta-Amyloid Peptides

In a study utilizing PeptideSyn technology, the synthesis of Amylin (1 - 37), human {KCNTATCATQRLANFLVHSSNNFGAILSSTNVGSNTY (Disulfide bridge: 2 - 7)} and human beta-amyloid (1-42) (H-DAEFRHDSGYEVHHQKLVFFAEDVGSNKGAIIGLMVGGVVIA-OH) using HCTU as an activator required a mere 15 hours of synthesis time, producing peptides of similar purity to those generated using traditional lengthy synthesis methods. Coupling yields for the peptide segment were an impressive 90–95%, showcasing the efficiency of PeptideSyn technology.
