Protein Expression

Protein Expression

Over the years, ProSpec has accumulated vast expertise in the development of bacterial-derived recombinant proteins. ProSpec’s Protein services are priced according to the required amount of strain comparison and optimization work needed. Our prices are based on a setup fee for expression analysis, the # of different strains (possibly with different helper plasmid systems) and the # of different culture conditions tested. ProSpec’s purified proteins exceed 90% purity as detected by SDS-PAGE analysis.  For specific pricing information, please contact sales@prospecbio.com
