We can custom produce milligram to multiple gram quantities of any protein or enzyme. In general, we use high fidelity PCR to amplify the gene of interest and clone the gene in a desired expression vector. Several recombinant clones are selected for DNA sequencing to obtain a clone with no mutations. Fermentation of the desired clone is performed at the desired scale (8 liters, 16 liters, 100 liters, 400 liters, 800 liters), and the protein is purified chromatographically according to the customer’s specifications, in order to obtain desired purity. Production can be customized to accommodate customer needs. Please contact customer service for a price quote.
