🔬 Peptide Manufacturing Process Overview

Step Details
🧱Solid-Phase Peptide Synthesis (SPPS) Peptides are synthesized step-by-step on an insoluble resin. Fmoc-protected amino acids are activated and coupled one at a time to build the peptide chain from the C-terminal to the N-terminal.
🔄Deprotection and Coupling Cycles Each cycle includes removal of the Fmoc protecting group (usually with piperidine) followed by the next amino acid addition using activating agents like HBTU/HATU in DMF solution.
✂️Cleavage from Resin Once the sequence is complete, the peptide is cleaved from the resin using trifluoroacetic acid (TFA), which also removes side-chain protecting groups.
🧊Crude Peptide Precipitation The peptide is precipitated from the cleavage solution by addition of cold ether or similar non-polar solvents to isolate it in solid form.
⚗️Acetate Salt Formation TFA residues are removed and the peptide is converted into an acetate salt using acetic acid or through ion-exchange desalting, improving peptide stability and reducing acidity.
🧪Purification (RP-HPLC) The crude peptide is purified using reverse-phase high-performance liquid chromatography (RP-HPLC) to isolate the desired product and eliminate side-products, usually achieving ≥98% purity.
❄️Lyophilization The purified peptide is dissolved in a suitable buffer or water, frozen, and then subjected to vacuum drying. This results in a lyophilized (freeze-dried) powder that is chemically stable and easy to store.
📊Analytical Characterization Final product quality is confirmed using analytical methods such as mass spectrometry (MS), analytical HPLC, and NMR to ensure proper identity, purity, and molecular integrity.
