Custom Antigens
Tailored antigen solutions for research, diagnostics, and assay development — covering recombinant and native sources across viral, bacterial, parasitic, and fungal classes.
Recombinant Antigens
We design and express recombinant proteins and peptides using validated expression systems to deliver high-purity antigens optimized for ELISA, lateral flow, immunogen, or vaccine R&D.
- Sequence-verified expression vectors
- Affinity-purified protein, QC tested (SDS-PAGE, WB, endotoxin)
- Delivered in buffer and concentration of choice

Native Antigens
Native antigens retain their authentic structure and epitopes, ideal for diagnostic and immunogenic assays. Produced under ethical sourcing and biosafety compliance.
| Pathogen Type | Description |
|---|---|
| Viral | Enveloped/non-enveloped viral antigens for serology and neutralization assays |
| Bacterial | Surface proteins, toxins, or lysates for diagnostic use |
| Protozoan/Parasitic | Stage-specific antigens for protozoa and helminths |
| Fungal | Cell wall and secreted proteins for antifungal assays |

Comprehensive Antigen Expertise
At Vaxonyx, we specialize in the design, expression, and purification of custom antigens tailored to meet the needs of research, diagnostics, and vaccine development. Our expertise covers both recombinant and native antigen production, enabling us to deliver biologically relevant and application-ready materials with superior quality and consistency.
Recombinant Antigens
We develop high-purity recombinant proteins using bacterial, mammalian, and insect cell expression systems. Each antigen is engineered for optimal yield, solubility, and native folding, ensuring performance across immunoassays, antibody generation, and functional studies. Sequence verification, purification optimization, and quality control (SDS-PAGE, Western blot, ELISA) are included in every project.
Native Antigens
Our team is experienced in isolating and purifying native antigens from a broad range of biological sources. These naturally derived proteins preserve authentic conformational epitopes, making them ideal for diagnostic assays and vaccine research.
- Viral pathogens – human and veterinary viruses for serological testing
- Bacterial species – surface and secreted proteins for immunoassays
- Protozoan and parasitic organisms – stage-specific or host-reactive antigens
- Fungal pathogens – cell wall and secreted antigens for antifungal studies
Veterinary Pathogens
In addition to human pathogens, we routinely develop antigens targeting veterinary infectious diseases, supporting diagnostics and vaccine research in livestock and companion animals.
