Creative Peptides has long-term peptide synthesis experience and rich expertise. We provide high-quality customized peptide synthesis services, from bulk API peptides, high-throughput library peptides, cosmetic peptides, to array peptides, antigen peptides, and other complex or abnormal peptide sequences.

  1. Applications

Synthetic peptides play a central role in MS-based protein discovery, characterization, and quantitative analysis, especially those proteins that serve as early disease biomarkers.

In addition, synthetic peptides also have important application prospects in clinical diagnosis and disease treatment.

  1. Methods & Quality

Our custom peptide synthesis services range from research grade to many API peptides. Creative Peptides is proficient in different synthesis methods to meet different needs.

> Liquid Phase Peptide Synthesis is used for the synthesis of short peptides (such as dipeptides).
> Solid Phase Peptide Synthesis is used to prepare biologically active peptides including long, difficult, and hydrophobic peptides.
> Biosynthesis provides many peptide modifications and customized peptides for diagnostic and therapeutic applications.

Peptide synthesis quality control

After peptide synthesis, each peptide is routinely analyzed by LC-MS, MALDI-MS, or HPLC to confirm the identity and quality of the customized peptide.

  1. MALDI-MS

    All peptides are analyzed by MALDI-MS to determine the molecular weight of the synthesized peptides.

  2. HPLC

    MALDI is an excellent method to determine the presence of the desired product, but it is not sufficient to determine purity. So, all non-crude peptides must be analyzed by reverse-phase HPLC (RP-HPLC) to determine purity. Other QC analysis, such as amino acid analysis, NMR, CE, and peptide content determination can be performed to confirm the quality of customized peptides.

  3. Extended quality control (optional)

    Chromatography (HPLC, TLC, GC, IC)

    Chromatography combined with mass spectrometry (LC-MS / ESI)

    Spectroscopy (UV-Vis, IR, NMR)

    Metal analysis (AAS, ICP, ICP-MS)

    Elemental analysis

    Titration (acid-base titration, Karl Fischer titration)

    Amino acid analysis

    Peptide sequencing
