Custom Peptide Synthesis Services | Science-Peptide Your Expert for Complex & Modified Peptides
Custom Peptide Synthesis Services
Why choose our Custom Peptide Synthesis Services?
1. With over 200 types of modifications, we can realize all your creative ideas.
Fluorescent labeling, biotinylation, PEGylation (the addition of polyethylene glycol chains), phosphorylation, glycosylation-regardless of the peptide modification you require, our Custom Peptide Synthesis Services have established protocols. Incorporation of non-natural amino acids, stapled peptides (peptides stabilized by chemical bridges), and multiple disulfide bonds (up to four pairs)-what others consider "high difficulty" is routine for our Custom Peptide Synthesis Services. Choosing Science-Peptide's Custom Peptide Synthesis Services means you can concentrate on scientific questions and leave the chemical challenges to us.
Real case: A client required synthesis of a 48-mer peptide containing 3 pairs of disulfide bonds ( "disulfide bonds"). Several companies quoted a turnaround time of three months with no guarantee of success. Through our optimized Custom Peptide Synthesis Services, we delivered the peptide within 15 days, with purity >95%, directly advancing the client's drug screening progress. This case fully demonstrates the advantages of our Custom Peptide Synthesis Services in synthesizing complex sequences.
2. Long peptides do not aggregate, and hydrophobic peptides do not precipitate.
Encountering long peptides with strong hydrophobicity and a tendency to aggregate ( "up to 189 amino acids"), we employ specialized solvent systems and synthesis strategies to ensure each peptide is correctly folded and stably dissolved. The more complex your sequence, the more valuable our Custom Peptide Synthesis Services experience becomes. By choosing our Custom Peptide Synthesis Services, even the most challenging sequences can be resolved efficiently.
3. Fast, but never at the expense of quality.
Standard peptides are shipped in 10–15 working days, with expedited service available in as fast as 5 days. However, speed is only part of the story-each batch undergoes dual validation by HPLC ( "High Performance Liquid Chromatography") and MS ("Mass Spectrometry"), ensuring precise purity and molecular weight. Optional analyses include amino acid analysis, endotoxin testing, and peptide content determination, with transparent data you can trust. Our Custom Peptide Synthesis Services are not only fast but also reliably high quality, which is why clients continue to choose us.
What can we do for you?
- Drug screening often requires a series of analogs: rapid synthesis, synchronized delivery, and support for SAR ("Structure–Activity Relationship") research. Our Custom Peptide Synthesis Services ensure batch-to-batch consistency.
- Immunology experiments require specific antigenic peptides: high purity, no cross-reactivity, stable batch performance, and precise sequences are provided through Custom Peptide Synthesis Services.
- Diagnostic reagents need labeled peptides: FITC ( "Fluorescein Isothiocyanate"), biotin, Cy series ( "Cyanine dyes"), with labeling efficiency >95%. Custom Peptide Synthesis Services integrate a variety of modification capabilities.
- Cosmetic raw material development Anti-aging, whitening, and hair growth peptide customization, supplied at kilogram scale, our Custom Peptide Synthesis Services cover the entire span from research and development to production.
- Complex structural research ("stapled peptides", "cyclic peptides"): with extensive experience and high success rates, our Custom Peptide Synthesis Services specialize in difficult peptide structures.
Meticulous service that goes beyond synthesis
Every project is managed by a PhD-level project manager, who understands both your scientific challenges and your time constraints. They closely follow your Custom Peptide Synthesis Services order throughout the process, ensuring smooth communication.
We proactively report progress on a regular basis, and any risks arising during synthesis are communicated in advance for joint decision-making. This level of transparency is rare in Custom Peptide Synthesis Services, but it is a steadfast commitment at our company.
Strict IP ( "Intellectual Property") protection, confidentiality agreements, and encrypted data systems ensure your molecules remain yours. Choosing our Custom Peptide Synthesis Services means choosing safety and trust.
They trust us
Key laboratory at Shanghai Jiao Tong University: required a 36-mer peptide with special modifications ( "special modifications") for structural biology research, which could not be synthesized by several companies. We delivered within two weeks, enabling their results to be published in a top journal with impact factor >112. This successful case demonstrates the research-grade quality of our Custom Peptide Synthesis Services.
GSK R&D Center, one of the world's top ten pharmaceutical companies: long-term collaboration, providing complex modified peptides for multiple early-stage projects, earning us their trust as a preferred Custom Peptide Synthesis Services partner. GSK's ongoing trust serves as the best endorsement of our Custom Peptide Synthesis Services capabilities.
From research to commercialization, we accompany you every step of the way.
Whether you are at the initial stage of exploring a new target or preparing to advance a candidate peptide to the clinical phase, Science-Peptide's Custom Peptide Synthesis Services are tailored to your requirements at every stage.
