Protein Expression & Production Services
Protein expression is almost universally used by research groups for a variety of purposes.
We offer comprehensive protein expression and purification services, ranging from small- to large-scale production, across five advanced platforms. Our solutions are competitively priced and include both standard packages and highly customized options. These advanced packages may involve testing tailored recombinant protein expression conditions across multiple systems in parallel, or optimizing extended production parameters within a specific system. Our end-to-end services encompass all stages, from gene synthesis and expression vector construction to pilot protein production in flasks, as well as large-scale protein expression using fermenters and bioreactors.
High-Throughput Protein Expression Condition Screening
Our high-throughput protein expression condition screening is designed to address challenges related to solubility, purity, functionality, productivity, refolding, or formulation. This approach leverages state-of-the-art technologies, processes, and tools to deliver optimal solutions. With extensive expertise in recombinant protein expression—including antibodies, enzymes, membrane proteins, cytokines, and more—from diverse species, CliniSciences has developed a robust and versatile toolbox to tackle these challenges effectively. Our commitment ensures best-in-class protein engineering services.
Choose guaranteed packages from the most reliable and innovative protein production partner in the industry.
