BiotechPack possesses the world's top peptide synthesis platform technology, including multiple automated peptide synthesizers, high-performance liquid chromatography (HPLC) systems, and mass spectrometers, ensuring that BiotechPack provides high-quality peptide products, fast delivery, and competitive prices. Since 2007, BiotechPack has gathered a synthesis team with multiple PhDs and Masters in organic synthesis as the backbone, providing over 100,000 high-quality custom peptides to scientists, researchers, and biotech companies worldwide. With years of experience accumulated in peptide synthesis technology, BiotechPack offers conventional linear peptide synthesis services and can meet the custom needs of various difficult, modified, and special peptides. BiotechPack focuses on quality control of mass spectrometry-grade peptides and customizes each peptide with care!
BiotechPack primarily uses the Fmoc synthesis method for peptide synthesis. The Fmoc method uses Fmoc as the α-amino protecting group, with side chain protection using benzylic alcohols. During synthesis, an Fmoc-amino acid derivative is covalently linked to the resin, Fmoc is removed with a base, the free amino terminal is neutralized with triethylamine, then the next amino acid is activated with DCC and coupled. Deprotection is often done using HF or TFMSA (trifluoromethanesulfonic acid) methods.
