KMD Bioscience’s protein expression services follow a standardized, end-to-end workflow. Customers need only provide the sequence, CDS, or name of the target protein, and our technical team will develop a comprehensive expression and purification protocol. The service process covers the entire chain, from gene synthesis, codon optimization, and expression vector construction, to host system selection (encompassing multiple platforms such as E. coli, yeast, insect cells, mammalian cells, and cell-free systems), and on to protein expression, purification, and subsequent quality testing. Leveraging a variety of fusion tag vectors and high-yield expression strains, KMD Bioscience is capable of flexible production ranging from milligram to gram scales and from pilot-scale to large-scale fermentation, while strictly controlling batch-to-batch consistency and product quality to provide customers with a one-stop solution from concept to finished product.
