LifeTein®, the custom peptide synthesis service company, has developed proprietary PeptideSyn technology. This technology provides a platform for continuous peptide synthesis using Fmoc and Boc chemistry, microwave technology, and a proprietary solid support resin. This is one of the many reasons why LifeTein® can offer low competitive pricing.LifeTein routinely uses our proprietary microwave technologies to produce peptides >100 amino acids. The longest peptide we have made to date is 169 amino acids. We promise to provide the HPLC purified peptide with the correct molecular weight analyzed by Electrospray ionization (ESI) Mass Spectrometry.LifeTein provides peptides with special modifications including Peptide Oligo Conjugate, Stapled Peptide, Stable Isotope Labeled Peptides, Peptide Nucleic Acids, Fluorescent Peptide: Cy3/Cy5/Cy7, Phosphorylated Peptide, Glycosylation, Peptide pool service, Biotinylated Peptides, Cell-Permeable Peptide, Cyclic Peptide, Long Peptide Synthesis: 169AA, MAP Peptide Synthesis, and D Amino Acid Peptide. LifeTein provides the fastest turnaround time and most reliable quality in the industry. Peptides are made in New Jersey, USA. Projects move from conception to bench in only 3-5 days so you can deal with your research deadlines.
