Creative Diagnostics offers Virus-like Particle (VLP) Antigen Production Services for VLP production for vaccine, diagnostic or immunological research applications. We have a rich experience in molecular biology, protein engineering and bioprocessing to deliver custom made VLP production for a wide range of applications, such as production of structurally authentic VLPs, optimal antigen presentation, epitope display and immunogenicity enhancement. Our advanced VLP production platform is equipped with high quality expression systems, validated purification procedures and advanced quality control technology to provide stable, robust and biologically relevant VLP antigens. We provide:
To meet the research and development demands for high-quality and structurally precise Virus-like Particle (VLP) antigens, we provide comprehensive Virus-like Particle (VLP) Antigen Production services. By leveraging high-level expression systems and sensitive characterization methods, we are able to efficiently produce and characterize VLPs that closely resemble their native structures and are able to present antigen in a highly effective way. This service includes tailored gene synthesis and expression approaches, purification with strict controls, and a range of analytical techniques (including electron microscopy, dynamic light scattering, ELISA, mass spectrometry, etc.) to ensure the highest quality of VLPs in terms of purity, stability, and immunogenicity. The platform is widely used for vaccine design and development, development of diagnostic assays, immunological studies, and therapeutic assessments. With our stringent quality control processes and extensive experience in the field, we are confident that every VLP production project we work on will have high specificity, reproducibility, and consistency. Our core services include:
Based on the target viral protein sequence, we optimize the design and synthesize gene fragments suitable for efficient expression, ensuring correct protein folding and assembly.
We offer a variety of expression systems (such as mammalian cells, insect cells, yeast, and plant cells) to customize VLP high-efficiency expression solutions based on customer needs.
Advanced co-expression and self-assembly technologies are used to ensure the correct assembly of viral structural proteins into stable virus-like particles.
Combining chromatography, ultrafiltration, and density gradient centrifugation techniques to achieve the production of high-purity and high-activity VLP products.
VLP morphology, particle size, purity, and antigenicity are comprehensively tested using various methods, including transmission electron microscopy (TEM), dynamic light scattering (DLS), nanoparticle tracking analysis (NTA), Western blot, and ELISA.
Assist in conducting in vitro and in vivo immunological experiments to evaluate the strength and specificity of the immune response induced by the VLPs.
We provide comprehensive services from laboratory-scale to pilot and industrial production, ensuring stable product quality and batch-to-batch consistency.
We support exogenous antigen fusion, multivalent display, and structural modification to meet specialized research and clinical application needs.
We provide full-scale project technical support, including protocol design, progress tracking, data analysis, and report writing, to ensure efficient project progress.
Design synthetic genes and construct expression systems to activate VLP protein expression.
Induce protein self-assembly to form structurally complete virus-like particles.
Purify VLPs and test particle size, morphology, and antigenicity.
Perform stringent quality control to ensure product purity and stability.
Analyze test data, generate reports, and provide technical support.
HPV VLP antigen ELISA immunoreactivity curve. The graph shows the absorbance (OD450) corresponding to different VLP antigen concentrations, reflecting the specific binding ability of the antigen and antibody and the immune activity. A smoothly rising curve indicates that our VLP antigen has good immunogenicity and high quality.
VLPs stand for "virus-like particles." They look very similar to real viruses, but they contain no viral genes, making them incapable of infecting you and extremely safe.
We use advanced protein expression and self-assembly technologies, combined with electron microscopy and other testing methods, to ensure that the VLP morphology and antigen structure are highly similar to those of the natural virus.
VLPs can be used for almost all viral vaccines, such as influenza, HPV, and hepatitis. Serological tests and immunological research are also suitable for VLP antigens.
From genetic design to purification, it takes about a few weeks. We can customize VLPs with different viruses or multivalent antigens to meet customer needs.
Of course, we have a mature process scale-up and quality control system that supports stable mass production from the laboratory to industrial scale.
