Plant based Vaccine Solution

What is a plant-based vaccine?

A plant-based vaccine is an innovative type of vaccine where antigens are produced within genetically engineered plants. Unlike conventional vaccines that rely on animal cells or eggs, this approach utilizes plants as "bioreactors" to express vaccine proteins. The process typically involves introducing genetic material encoding the desired antigen into plant cells, which then produce the vaccine component as they grow.

Plant-based vaccines offer several compelling advantages: they are economically effective to produce, carry minimal contamination risks from animal pathogens, are easy to scale up rapidly to meet demand, and boast simple storage requirements without the need for complex cold chains.

Antigen Prediction System Platform

Our Antigen Prediction System Platform integrates advanced bioinformatics and computational biology tools to identify and prioritize immunogenic antigens. Leveraging cutting-edge algorithms, we analyze pathogen genomes or cancer markers to predict key epitopes that elicit robust immune responses. This platform enables the rational design of vaccines by pinpointing high-potency antigens, significantly accelerating the development process for bacterial, viral, fungal, parasitic, and cancer-targeted vaccines. By combining traditional immunology with state-of-the-art predictive modeling, we ensure optimal antigen selection for maximum immunogenicity and efficacy.

Protein Expression Platform

The Protein Expression Platform at Creative Biolabs offers versatile solutions for producing recombinant antigens using multiple expression systems. We specialize in optimizing bacterial (e.g., E. coli), yeast, insect, and mammalian cell systems to meet diverse production needs. Our expertise in genetic engineering allows us to tailor expression vectors, culture conditions, and purification protocols for high-yield, biologically active proteins. Whether for preclinical research or large-scale manufacturing, our platform ensures consistent production of immunogenic proteins, supporting the development of vaccines with enhanced stability and immunogenicity. We seamlessly integrate expression technologies with downstream analytical and formulation services to streamline the vaccine development pipeline.

Modular Delivery System Platform

Our Modular Delivery System Platform is designed to enhance vaccine potency and delivery efficiency through customizable, multi-component formulations. Focused on optimizing delivery mechanisms, we develop lipid-based nanoparticles, viral-like particles (VLPs), and other nano-carriers to protect antigens, improve cellular uptake, and modulate immune responses. The modular design allows for precise integration of adjuvants, targeting ligands, and protective matrices, enabling tailor-made systems for various vaccine types—from prophylactic to therapeutic.
