Adjuvant Efficacy

Our Protein Biochip technology offers a high-efficiency, precise approach to evaluating the immunopotentiating effects of adjuvants in vaccine development.

Why Adjuvant Potency Matters

Adjuvants are components added to vaccines to amplify immune responses. By employing various mechanisms, adjuvants enhance antigen presentation and recognition by the immune system, thereby improving the vaccine's efficacy in combating pathogens.

Adjuvants not only boost vaccine efficacy but also help reduce the required antigen dose per shot, minimize the number of vaccinations, and, in some cases, improve the stability of antigen components. While antigens are the primary source of a vaccine's immunogenicity, adjuvants significantly enhance the intensity, breadth, and durability of immune responses.

This is especially crucial in therapeutic vaccines, such as cancer vaccines, and for populations like the elderly, where immune responses often need additional support. Moreover, adjuvants can modulate the type of immune response-enhancing humoral immunity (e.g., antibody production) or bolstering cellular immunity (e.g., T-cell responses)-which plays a critical role in immunogenicity assessment.

Whether it's for influenza, COVID-19, tuberculosis, or cancer vaccines, our Protein Biochip platform supports accurate evaluation of adjuvant potency across all vaccine development scenarios.

How We Support Your Vaccine Development

Our advanced Protein Biochip technology enables comprehensive analysis of adjuvant efficacy throughout the vaccine development process:

Adjuvant-Antigen Interaction Analysis: We provide in-depth insights into the interactions between adjuvants and antigens. This analysis helps elucidate the mechanisms through which adjuvants function within the immune system and optimize their pairing with antigens. For instance, during COVID-19 vaccine development, we can evaluate the effectiveness of different adjuvants (e.g., liposomal adjuvants or oil-in-water emulsions) in activating antibody responses and T-cell immunity, ensuring the best adjuvant formulation.

Immunogenicity Evaluation of Various Adjuvants: Our Protein Biochip allows simultaneous detection of multiple immune responses, including antibody production, T-cell activation, and memory formation. For example, in influenza vaccine development, we can help compare the immunogenic potency of aluminum adjuvants, AS01 adjuvants, and MPL adjuvants in different formulations.

Monitoring Cytokines and Immune Biomarkers: Real-time monitoring of cytokine responses induced by adjuvants-such as TNF-α, IL-6, and IFN-γ-is critical. This is particularly important for cancer vaccines, where adjuvants regulate the immune microenvironment to enhance T-cell anti-tumor responses.

Array Example

Panel Name	Marker Combination	Target Application	Possible Sample Preparation
Th1/Cell-Mediated	IFN-γ, IL-2, IL-12 (p70), TNF-α, IL-15	Evaluate Th1-biased response and cell-mediated immunity (CMI)	- In vitro: Supernatants from stimulated PBMCs or splenocytes - In vivo: Serum or plasma, tissue homogenates
Th2/Humoral	IL-4, IL-5, IL-10, IL-13, GM-CSF	Assess Th2-biased response and humoral immunity	- In vitro: Supernatants from B-cell or PBMC cultures - In vivo: Serum (for cytokines and antibody titers)
Pro-inflammatory	IL-1β, IL-6, TNF-α, CXCL10 (IP-10), IL-8 (CXCL8)	Track early innate immune activation and potential inflammatory side effects of adjuvants	- In vitro: Macrophage or DC culture supernatants - In vivo: Serum, local tissue (e.g., injection site homogenates)
Th17/Autoimmunity	IL-17A, IL-21, IL-22, TGF-β, IL-23	Characterize adjuvants that may induce or modulate Th17 responses (e.g., beneficial vs. autoimmunity risk)	- In vitro: T cell or PBMC cultures - In vivo: Serum or ex vivo restimulation supernatants from lymphoid organs
Regulatory	IL-10, TGF-β, IL-2 (for Treg expansion), FoxP3 (if using cell-based array/flow), IL-35 (in some advanced regulatory contexts)	Assess whether adjuvant promotes regulatory mechanisms or dampens excessive responses	- In vitro: Treg or PBMC cultures - In vivo: Serum, Treg sorting from spleen/lymph nodes and subsequent protein analysis
