Protein Expression Services

Over years of development, KMD Bioscience has established a complete system for Recombinant Protein Expression and Purification, Protein Fermentation, and Process Technical Support for both Small-scale and Pilot-scale Protein Production. Our scientists all come from biopharmaceutical enterprises and have 5–8 years of experience in the development of therapeutic proteins. They have in-depth knowledge of the development process for recombinant protein products under GMP regulations, QC quality control systems, documentation traceability, as well as ICH and GMP guidelines.

KMD is committed to providing users with high-purity and low-cost recombinant protein reagents, such as proteins, cytokines, various receptors, biological toxicity genes, viral antigens, transcription factors, hormones, etc., to meet the different needs of midstream and downstream research experiments. The proteins delivered by KMD can be used in drug research, antibody preparation, animal experiments, ELISA, crystal structure research, in vitro enzyme activity assays, cell experiments, etc. We have been dedicated to the research of Recombinant Protein Expression and Production for many years. Our scientists have extensive experience in Yeast Recombinant Protein Expression, Fermentation, and Purification, and are able to quickly customize yeast protein expression strategies for different clients. At the same time, we can provide multiple specifications of yeast fermentation scales, such as 500L fermenters. Combined with our Protein Purification Platform, we are able to obtain high-quality recombinant protein products within a relatively short cycle.

In Vitro Recombinant Protein Expression and Production usually involve technical details such as the selection of expression hosts, gene synthesis, and vector construction. Clients only need to provide us with a protein sequence, CDS, or protein name, and our experienced scientists can formulate a complete Protein Expression and Purification Plan for you in a short period of time.
