Protein Purification: (Medium and Large Scale) We specialize in protein expression in bacterial and insect cells expression systems. Proteins can be purified as soluble proteins with and without tags or as inclusion bodies which can be refolded as required. We have worked out a number of refolding methods that allow us to isolate refolded proteins that are as functional as those produced in the soluble fractions.
