In the evolving world of biotechnology and molecular science, custom peptide synthesis services are vital for advancing research, diagnostics, and therapeutic development. From basic linear peptides to complex modifications, custom synthesis ensures precise, high-purity peptides tailored to meet the unique demands of laboratories, pharmaceutical companies, and academic institutions.
Whether you require small-scale peptides for screening studies or large-scale production for clinical applications, custom synthesis services provide flexibility, consistency, and scientific control over every stage of the peptide production process.
What Is Custom Peptide Synthesis?
Custom peptide synthesis refers to the chemical or enzymatic creation of peptide chains based on user-defined amino acid sequences. This process enables researchers to generate specific peptides that are not readily available through commercial catalogues.
These services typically include synthesis, purification, quality testing, and delivery of peptides tailored for specific experimental or therapeutic purposes.
Why Use Custom Peptide Synthesis Services?
While some peptides can be purchased pre-made, many projects demand precise specifications. Here are common reasons researchers and developers turn to custom synthesis:
- Novel Sequences: Target peptides not found in commercial libraries
- High Purity Requirements: Eliminate impurities that may affect data accuracy
- Labeling & Modifications: Add fluorescent tags, phosphorylation, or biotin for tracking or interactions
- Bulk Quantities: Manufacture gram-scale or kilogram-scale peptides for scale-up studies
- Custom Lengths: From short 5-mers to long 100+ amino acid chains
Peptide Synthesis Techniques
Several techniques are employed in custom peptide synthesis. The choice of method depends on the length, complexity, and purpose of the peptide:
1. Solid-Phase Peptide Synthesis (SPPS)
The most common method, SPPS builds peptides sequentially on a solid resin support, allowing for rapid and automated assembly. It supports long sequences and diverse modifications.
2. Liquid-Phase Peptide Synthesis
Used for large-scale industrial production, this method offers high yields and is ideal for short peptides with fewer modifications.
3. Recombinant Expression
Suitable for producing very long peptides or peptide-like proteins using bacterial or yeast systems. This method is often used for therapeutic or vaccine development.
Purification and Quality Control
After synthesis, peptides are rigorously purified and analyzed. Quality assurance steps include:
- High-Performance Liquid Chromatography (HPLC): Used to purify peptides to the desired purity level (typically 70%, 85%, 95%, or >98%)
- Mass Spectrometry (MS): Confirms molecular weight and sequence fidelity
- Amino Acid Analysis: Verifies the identity and composition of synthesized peptides
- UV Spectroscopy: Quantifies peptide concentration
- SDS-PAGE: Checks molecular size and uniformity (for larger peptides)
Available Modifications and Formats
Custom peptide services offer a wide variety of chemical and structural modifications to meet experimental needs:
- Terminal Modifications: Acetylation, amidation for increased stability
- Fluorescent Labels: FITC, TAMRA, or Cy dyes for imaging applications
- Phosphorylation or Methylation: Simulates post-translational modifications
- Biotinylation: Enables peptide affinity studies
- Cyclization: Enhances structural rigidity and protease resistance
- D-Amino Acids: For improved stability and bioavailability
Peptides can also be delivered in lyophilized powder, pre-dissolved solution, or conjugated form, based on user requirements.
