Recombinant protein technologies have generated numerous broad range proteins from different species, that plays an important role in academic research and drug discoveries. Currently, there are four widely used cell based expression systems: mammalian, yeast, insect and bacterial (E.coli) cells. OriGene has successfully purified more than 10,000 proteins from all of these systems. The final protein products can be provided in various formats: crude cell lysates, purified tagged or untagged proteins, and heavy labelled MS standards.
OriGene offers comprehensive, high quality recombinant custom protein services from different expression systems, in addition to the standard catalog items. Our proprietary protein expression/purification technology maximizes the purity and yield of target proteins in different systems. Our goal is to provide a flexible service program tailored to your needs every step of the way. We offer a complete ‘start to finish’ service from the cDNA (gene) cloning step to the protein purification step, and downstream modifications such as tag addition-removal, endotoxin testing/removal, conjugations, and any other services that you may request. Choose OriGene as your reliable partner for your protein related research and we can help you accelerate your discovery in a timely and cost-effective manner every step of the way, at a very affordable price.
