mRNA Vaccine Research Solutions

mRNA vaccines represent a groundbreaking immunization technology harnessing the biological properties of messenger RNA (mRNA) to induce immune responses. These vaccines consist of a segment encoding a specific antigenic protein's mRNA sequence. Typically, the antigenic protein is a crucial surface protein of a pathogen, such as the spike protein of coronaviruses or the hemagglutinin protein of influenza viruses. Once introduced into the body, the mRNA guides cells to produce these antigenic proteins, triggering an immune response and effectively preventing diseases. Compared to traditional vaccines, mRNA vaccines offer advantages in rapid development, a relatively straightforward and swift production process, and exceptional safety and efficacy.

With years of expertise in protein, antibody, and ELISA kit development, CUSABIO possesses an extensive range of research reagents for viral studies and provides high-quality technical services. We are dedicated to supporting various stages of mRNA vaccine development, including early-stage research, production, quality control, and immune potency testing. Our commitment is to advance the progress of mRNA vaccine research.

Production Process

In the manufacturing of mRNA vaccines, plasmids serve as carriers, into which foreign genes are inserted, followed by transcription and translation processes to generate the corresponding mRNA. CUSABIO provides a Plasmid DNA Purification Maxiprep Kit, enabling you to rapidly and efficiently extract and purify plasmid DNA, thereby supplying the necessary raw material for mRNA vaccine production. The extracted and purified plasmids can be used in subsequent experiments, such as enzyme digestion and transfection, to generate mRNA with specific sequences.

Quality Control

Once mRNA is translated into functional antigenic proteins, it induces the production of antigen-specific immune responses in the body, forming immunological memory. The second edition draft of the United States Pharmacopeia's mRNA Vaccine Quality Analysis (Analytical Procedures for mRNA Vaccine Quality) mentions that a functional binding assay (cell-based assay) for the expressed protein in transfected cells can be employed to demonstrate the efficacy of mRNA-LNP (confirm the integrity of mRNA molecules and demonstrate critical epitopes of the expressed protein).

The product-specific assessment of proteins encoded by RNA can be analyzed through cell-based protein expression methods, such as the ELISA approach. ELISA methods enable the detection of protein expression at the cellular level and the evaluation of the binding functionality of the expressed protein.

Utilizing ELISA methods for assessing the functionality of antigenic proteins encoded in mRNA vaccines during the quality control phase is a crucial means to ensure vaccine safety and efficacy. Through this detection method, the performance and quality of the vaccine can be evaluated, providing robust support for subsequent clinical trials and production. CUSABIO offers various common virus antigen ELISA kits with high sensitivity and specificity, suitable for performance and quality assessment during the quality control phase of vaccine development.

Immune Potency Testing

During the immune potency testing phase of mRNA vaccine development, multiple indicators are examined, including antibody levels, cellular immune responses, secretion of cytokines and chemokines, specific antibody production, immune memory, and cross-reactivity. By comprehensively analyzing these indicators, it is possible to understand the characteristics of the immune response and protective effects induced by the vaccine, providing crucial information for vaccine development and improvement.

● Cytokine and Chemokine Detection

Cytokines are crucial regulatory factors in the immune system, playing a key role in the immune response process. Detecting immune-related cytokines and chemokines produced by cells after vaccine administration helps to understand the characteristics and mechanisms of the immune response induced by the vaccine.

Virus Neutralizing Antibodies

Neutralizing antibodies can bind to antigens on the surface of a virus, directly preventing the virus from attaching to target cell receptors and thus blocking viral entry into host cells. Neutralizing antibodies are typically generated in animals infected with the pathogen, and one of the prerequisites for successfully preparing neutralizing antibodies is the production of highly effective and specific antisera. CUSABIO employs in-house adjuvants and has established an efficient antibody screening mechanism, offering customization services for virus neutralizing antibodies based on customer requirements.
