Bacteria ☆☆☆☆ ☆☆☆☆ ☆☆☆
Yeast ☆☆☆ ☆☆ ☆☆☆☆ ☆☆
Insect ☆☆ ☆☆☆ ☆☆☆☆
Mammalian cells ☆☆☆ ☆☆☆☆ ☆☆☆☆ ☆☆

Team and Capacity

To ensure the best quality of our antibody and protein production service, including the highest purity of the product and the lowest risk of contamination, Creative Biolabs has developed several platforms supported by our recombinant protein production scientists. In addition, we also have quality control lab, molecular biology lab, etc. Our experienced experts will ensure to deliver protein products that fit our clients’ initial specifications.

Our Antibody and Protein Production Services

We offer small to large-scale protein expression and purification services through 5 platforms as shown in above table at a competitive price. In the meanwhile, we provide advanced and custom service portfolio including screening in different expression systems in parallel or in different expression conditions in a given system. Our comprehensive service includes all phases from gene synthesis, vector construction to small scale protein production in flasks and large-scale protein production in bioreactors and fermenters.

We are committed to overcoming all potential obstacles related to solubility, refolding, purification, formulation, functionality and productivity, even for challenging proteins. With vast experience in the recombinant protein expression, such as enzymes, cytokines, or membrane proteins, etc. and antibodies including monoclonal antibody, bispecific antibody, anti-idiotype antibody, antibody-drug conjugates, etc., Creative Biolabs has developed complete production platforms to tackle any challenge in combination with discovery, engineering, bioassay and assay development, etc. For detailed information, please visit the following modules.
