About QYAOBIO
Our Story
QYAOBIO was established in 2008 by biochemist Wang Xiping in Shanghai’s Zhangjiang Hi-Tech Park, one of China’s premier life science clusters. What began as a small peptide synthesis laboratory has grown into a full-service biotechnology manufacturing company serving research institutions across more than 30 countries.
For 18 years, we have focused exclusively on the research-grade market — providing custom peptides, antibodies, and recombinant proteins to academic laboratories, pharmaceutical R&D teams, and biotechnology companies. We do not manufacture for clinical or therapeutic use, which allows us to maintain rigorous quality standards tailored specifically to the demands of research and preclinical development.
Our team combines deep expertise in synthetic chemistry, immunology, and molecular biology. Senior chemists average more than 12 years of peptide synthesis experience, and our project managers are themselves scientists who understand the experimental context behind every order.
Manufacturing Capability
We operate a modern synthesis and analytical facility in Shanghai capable of handling projects at every scale:
- Peptide Synthesis: Sequences from 5 to 150 amino acids, from milligram research quantities to kilogram production batches
- Success Rate: Greater than 95% first-pass synthesis success across standard and modified peptides
- Modification Library: Over 400 validated modification methods, including phosphorylation, biotinylation, PEGylation, cyclization, stapling, fluorescent labeling, and unnatural amino acid incorporation
- Analytical Equipment: In-house HPLC, LC-MS, and mass spectrometry for real-time quality verification

Quality Commitment
Quality is not an afterthought — it is integrated into every stage of production. Our ISO 9001-certified quality management system, maintained since 2012 and audited annually, covers:
- Raw material incoming inspection and supplier qualification
- In-process monitoring at each synthesis step
- Final product testing with HPLC purity analysis and LC-MS identity confirmation
- Full Certificate of Analysis (COA) documentation for every shipment
- Annual third-party audits of our quality system
Each batch record is archived for full traceability. Customers can request historical QC data for repeat orders, enabling direct comparison of lot-to-lot consistency — a capability that pharmaceutical discovery teams and academic laboratories alike depend on for reproducible results.
Research Collaborators
QYAOBIO’s products and services support research at leading institutions worldwide:
- Chinese Academy of Sciences — Peptide and protein reagents
- Tsinghua University — Modified peptide synthesis
- Stanford University — Custom antibody development
- Harvard University — Research-grade recombinant proteins
- MIT — Specialty peptide modifications
- University of Oxford — Peptide libraries
- Imperial College London — Antibody engineering support
These collaborations reflect the trust that leading researchers place in our quality and reliability.
Our customers’ work has appeared in numerous peer-reviewed publications across disciplines including medicinal chemistry, immunology, structural biology, and neuroscience. While we do not disclose customer-specific projects, the breadth of applications — from basic epitope mapping to advanced peptide-drug conjugate development — demonstrates the versatility of our manufacturing platform.
Core Values
Precision. Every peptide, every antibody, every protein is manufactured to exact customer specifications. We verify purity and identity at every stage — no exceptions. When a researcher depends on a reagent for a critical experiment, there is no room for “close enough.”
Innovation. Our 20+ patents and 400+ modification methods represent continuous investment in expanding what is possible in peptide chemistry. We tackle challenging sequences that other manufacturers decline. Our R&D team regularly develops custom modification protocols for unique customer requirements.
Integrity. We deliver what we promise. Every product ships with complete analytical documentation. If a synthesis presents challenges, we communicate transparently and work with our customers toward a solution — rather than delivering a substandard product or staying silent about issues.
Our Customers
QYAOBIO serves a diverse community of researchers:
- Academic laboratories requiring small quantities of high-purity peptides for mechanistic studies, structural biology, and publication-quality data
- Pharmaceutical R&D teams running lead optimization and SAR programs that demand rapid, reliable peptide supply
- Biotechnology companies developing research reagents, assay components, and preclinical candidates
- Core facilities and CROs outsourcing peptide and antibody production for their internal clients
Our customer retention rate — the percentage of researchers who return for subsequent orders — exceeds 85%, reflecting the consistency and reliability of our service.
Frequently Asked Questions
How long has QYAOBIO been in operation?
QYAOBIO was founded in 2008 and has been continuously operating for 18 years as a specialized peptide and antibody manufacturer.
What certifications does QYAOBIO hold?
We are ISO 9001 certified for our quality management system. Our facility undergoes annual third-party audits to maintain this certification.
Do you have a minimum order quantity?
No fixed minimum. We handle orders from small research quantities (milligrams) to production-scale batches (kilograms). Each project receives individual attention regardless of size.
Where do you ship to?
We ship to research institutions in over 30 countries across North America, Europe, and Asia-Pacific. Lyophilized format is standard for peptides to ensure stability during transit.
Can I visit your facility?
We welcome visits from established research partners and institutional clients by appointment. Please contact Dr. Aaron Wang at aaron@senobiocorp.com to arrange.
What is your approach to intellectual property?
All customer sequences, targets, and project details are treated as confidential. We execute Non-Disclosure Agreements (NDAs) as standard practice before project initiation. Your intellectual property remains yours — we do not claim any rights to customer sequences or research outputs.
