Visualize and Model Pathogenesis

Before a vaccine can be generated and scaled, one must first understand the pathogen and its effect on the host. What is the pathogen’s life cycle in the host? What is the host’s immune response? Presumably the host’s immune response failed. Why?  This requires preclinical research using human samples. Together, Bio-Techne’s brands provide solutions for quantifying pathogen/host nucleic acid and protein changes during infections.


Localize and Visualize the Pathogen in the Host

Use antibodies to visualize the local context of the host during pathogen infection. Quality antibody products are built for reproducibility based on the 5 pillars of antibody validation: Genetic Strategy Validation, Orthogonal Validation, Independent Antibody Validation, Expression of Tagged Proteins Validation, and Biological Strategies Validation.

Use RNAScope® in situ hybridization to visualize pathogen RNA in the host. Compare pathogen load in infected tissue to that in uninfected tissues.

Understand the Pathogen Life Cycle and its Effect on the Host


Understand Why the Immune System Fails

Understand why the immune system failed to respond appropriately to the pathogen using Immunoassays  and Tocriscreen Libraries.

Use cell culture as a  model system to understand host cell responses.

     Cell Culture Media

     Cell Expansion Kits

     Cell Selection Kits

Use biologically active proteins as immunogens to understand mechanisms of the host cell response.

Assess Vaccine Quality

What type of vaccine are you manufacturing? Cell culture is a useful tool for developing and assessing vaccine efficacy and safety. What type of immune response are you trying to stimulate? In addition to addressing these questions, one needs to choose clones with the ideal manufacturing characteristics such as robust cell growth and scalability.

GMP Proteins

Culture and Isolate the Vaccine

Culture antigen producing cells using GMP cytokines and growth factors. Transition to GMP proteins as early as possible for consistency as you develop your vaccine.

Create stable overexpressing cell lines using the TcBuster™ transposon delivery system. TcBuster has an insertion efficiency greater than 50%, improved viability and cellular expansion and no inadvertent transpositions.

Use Single-Cell Western Assays to verify monoclonality. Single cell western can also be used to evaluate isoform heterogeneity. Measure protein expresson in 1000 cells in 4 hours.

Micro-Flow Imaging (MFI) Particle Analysis Instrument by ProteinSimple

Vaccine Analytical Process Development

Use Simple Western and Maurice and iCE to assess purity, and identity of samples. Assess molecular weight to infer aggregation, fragmentation, degradation. Assess charge heterogeneity, a proxy for oxidation, glycation, deamidation, disulfide connectivity or translation fidelity.

Visualize polysaccharides with glycobiology enzymes via fluorescence.

Vaccine Formulation Assessment and Stability Testing

Use Maurice and iCE to assess formulation. iCE can be used to quickly and accurately monitor charge variants, which is important for evaluating vaccine stability and efficacy. 

Use Micro-Flow Imaging (MFI) to quickly detect and distinguish subvisible particles. MFI can also be used for protein aggregation analysis, which is important for assessing vaccine stability. MFI  is more sensitive than traditional techniques and allows you distinguish between protein aggregates and and other particulates.  

Profile Immune Response to the Vaccine

Assess vaccine efficacy by visualizing pathogens in tissues collected from experimental animal model systems. Monitor the Immune response in animal models and human samples in order to evaluate vaccine utility and anticipate adverse immune responses to the vaccine.

Luminex Flexmap 3D multiplex instrument

Discover and Verify Immune Response to Antigen

Build the Luminex® assay that you need to detect up to 100 target analytes simultaneously.  

Use QuantikineTM ELISAs to validate one or two immune responses over the long term. Learn about other ELISA Kits in our portfolio.

Use RNAScope in situ hybridization to evaluate vaccine efficacy in animal model systems. Compare pathogen load in samples from vaccinated animals to that of unvaccinated animals.
