Custom Peptide Synthesis
Peptide synthesis expertise
SB-PEPTIDE is specialized in chemical peptide synthesis. Solid-Phase Peptide Synthesis (SPPS) consists in conjugating several amino acids (c.f. amino acids chart) to obtain a peptide chain. SB-PEPTIDE offers to synthesize simple to complex peptides (highly hydrophobic sequences, highly hydrophilic, long sequences, cyclized peptides, conjugations or modifications), for occasional or recurrent projects. SB-PEPTIDE can synthesize individual peptides (purified or not), proteins and peptide libraries (96 wells plate).
Custom synthesis of individual peptides
SB-PEPTIDE offers several standard synthesis scales (from mg to multi-grams) and purity rates for custom peptide synthesis.
Standard synthesis scales and purity rates
Any other scales (intermediates or multi-grams) are of course possible, as well as specific purity rates. Feel free to ask the best format for you when submitting your quote request.
Thanks to the use of chemical routes for peptide synthesis, unlimited modifications are possible on individual peptides, including on small proteins. Discover some of the available peptide modifications here.
Custom peptide synthesis in 10 days
Custom peptide synthesis is a multi-step prossess, starting from the chemical synthesis of a crude peptide, its purification, eventual modifications, preparation for delivery with quality controls all along the process. SB-PEPTIDE usually delivers standard peptides in 4 weeks.
In case of urgent needs, SB-PEPTIDE has been the first peptide company (to its knowledge!) to offer a 10 days express production service. The peptide express service is also available for modified and purified peptides. Visit peptide synthesis express service here.

Solid Phase Peptide Synthesis. I. The Synthesis of a Tetrapeptide
Synthesis of proteins by native chemical ligation.
A simple technique has been devised that allows the direct synthesis of native backbone proteins of moderate size. Chemoselective reaction of two unprotected peptide segments gives an initial thioester-linked species. Spontaneous rearrangement of this transient intermediate yields a full-length product with a native peptide bond at the ligation site. The utility of native chemical ligation was demonstrated by the one-step preparation of a cytokine containing multiple disulfides. The polypeptide ligation product was folded and oxidized to form the native disulfide-containing protein molecule. Native chemical ligation is an important step toward the general application of chemistry to proteins.
