With the rapid development of biopharmaceuticals, synthetic biology, and industrial biotechnology, recombinant proteins have become a core product type in modern industrial systems. Traditional protein expression systems, such as E. coli, yeast, or mammalian cells, face challenges in large-scale production, including low expression levels, high production costs, difficulties in scaling up, and the risk of viral contamination. As a natural protein storage tissue, rice endosperm enables efficient accumulation and stable preservation of recombinant proteins, and the rice endosperm expression and purification system offers significant advantages for recombinant protein production.

Lifeasible possesses years of experience in recombinant protein expression research and services. We consistently stay at the forefront of advancements in this field and have established a bioreactor platform based on rice endosperm cells. This platform provides an integrated solution spanning from gene design to industrial-scale production, offering clients efficient, safe, and scalable recombinant protein expression and purification services.

Our Rice-Derived Recombinant Protein Expression and Purification Platform

Recombinant Protein Expression

Based on an advanced rice endosperm-specific expression system. We utilize molecular biology and plant genetic engineering techniques by introducing the gene encoding the target protein into the rice genome to achieve high-level, specific expression in endosperm tissue. This platform utilizes the following key mechanisms to achieve efficient expression.

• Endosperm-specific promoter-driven expression. By using specially optimized promoters, we achieve targeted expression of the target protein in endosperm, significantly improving expression efficiency.
• Proteome storage. Recombinant proteins are directed into and stored within proteomes specific to rice endosperm. This natural encapsulation mechanism not only protects the protein’s biological activity but also prevents degradation by endogenous cellular proteases.
• Downstream Processing. By integrating mature protein separation and purification processes, we extract high-purity target proteins from dehulled rice, ensuring the final product meets all industry standards.

Recombinant Protein Purification

Optimizing extraction and chromatography processes enables efficient separation of endogenous rice proteins. We support a wide range of scales, from laboratory research (milligram scale) and small-scale pilot and pilot-to-scale upscaling (gram scale) to large-scale production, ensuring seamless integration and linear scalability of the process across different stages.
