Solid phase peptide synthesis (SPPS) offers important advantages over the synthesis in solution, in that coupling reactions can be carried out more rapidly and nearly to completion using an excess. This protocol for solid-phase peptide synthesis (SPPS) is based on the widely used Fmoc/tBu strategy, activation of the carboxyl groups by aminium-derived coupling reagents and use of PEG-modiﬁed polystyrene resins. A standard protocol is described, whic Synthetic peptides are important as drugs and in research. Currently, the method of choice for producing these compounds is solid-phase peptide synthesis. In this nonspecialist review, we describe the scope and limitations of Fmoc solid-phase peptide synthesis. Furthermore, we provide a detailed protocol for Fmoc peptide synthesis
Although these new approaches are impressive and have been employed successfully for the synthesis of many proteins, general protein chemical synthesis is still not routine and there are still many challenges that remain to be confronted. Methods for synthesizing peptides are divided conveniently into two categories: solution and solid-phase Die erste Festphasensynthese von Peptiden auf festen Polymeren als Substrate wurde 1966 von Bruce Merrifield und Arnold Marglin mit der Merrifield-Synthese am Beispiel von Insulin durchgeführt

In peptide synthesis, an amino-protected amino acid is bound to a solid phase material (most commonly, low cross-linked polystyrene beads), forming a covalent bond between the carbonyl group and the resin, most often an amido or an ester bond. Then the amino group is deprotected and reacted with the carbonyl group of the next amino-protected amino acid. The solid phase now bears a dipeptide. Figure 2. Mechanism for removal of a Boc protecting group from the N-terminus of a growing peptide chain using trifluoracetic acid (TFA). Several years after Merrifield's introduction of the Boc SPPS strategy and using chemistry pioneered by Louis Carpino, Atherton and Sheppard applied the Fmoc amine protecting group to solid phase peptide synthesis Peptides are gaining considerable attention as potential drugs. The so-called Fmoc/ t Bu solid-phase synthesis is the method of choice for the synthesis of these molecules in both research and industrial settings
. Peptides are manufactured using solid phase FMOC or BOC chemistry methodologies on a PEG-Polystyrene support resin. Upon synthesis completion, side chain protecting groups are removed and the peptides are simultaneously cleaved from the resin. The cleaved and deprotected peptide material is then precipitated, washed and dissolved in a buffer containing H2O/ACN/HOAC prior to lyophilization Order histone peptide from Sigma-Aldrich.

Solid-phase synthesis has its origins in the pioneering work of Merrifield and involves the stepwise addition of nitrogen-protected amino acids to a peptide chain that is anchored to a polymeric support. The products of this method are sequence-specific peptides that can be isolated as pure materials
Solid-phase synthesis is the most common technique for peptide synthesis. Usually, peptides are synthesized from the carbonyl group side (C-terminus) to amino group side (N-terminus) of the amino acid chain in this method, although peptides are synthesised in the opposite direction in cells In solid phase synthesis, the peptide is constructed on resins (e.g., polystyrene, polyacrylamide, PEG). The key advantage with solid phase is the ability to synthesize peptides which don't lend themselves to bacterial expression using solution phase techniques. One of the major challenges facing solid phase synthesis, however, is yield - as the size of the peptide increases, yields. Solid-Phase peptide synthesis Peptides were synthesized manually using a syringe fitted with a porous polyethylene disc and attached to a vacuum trap for easy filtration Solid-phase peptide synthesis The purpose of this step is to sequentially add amino acids to the resin to build a peptide chain. There are two main steps in coupling an amino to peptide chain. The first step is deprotecting Fmoc from the amino on the resin to expose an amine. The second step is coupling an activated amino acid to the exposed amine. These steps are done exactly the same on 2. 1. Tanpakushitsu Kakusan Koso. 1968 Jun;13(7):651-8.

Solid-phase peptide synthesis (SPPS) 2.1 Initial aspects of the peptide synthesis: N-terminal amino acid protecting group The general process for synthesizing peptides on a resin starts by attaching the rst amino acid (AA), from the C-terminal residue (carboxyl group), then proceeding with the peptide sequence construction to the N-terminal end. The amino acids are coupled to the supported. Solid-phase peptide synthesis involves only a limited number of undesirable components—by-products. However, the identification and removal of these undesirable components can be problematic. Acidolytic cleavage yields a crude product containing both the desired peptide and impurities, such as deletion peptides, truncated peptides, incompletely deprotected peptides, modified peptides.
