Custom Protein Service

Recombinant protein technologies have generated numerous 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 cells. OriGene has successfully purified more than 10,000 proteins from all of these systems. The final protein products are provided in various formats: crude cell lysates, purified proteins, and heavy labeled MS standards.

In addition to the standard catalog items, OriGene also offers high quality custom protein services from different expression systems. 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. Our goal is to provide a flexible service program tailored to your needs every step of the way. 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.

Customer testimonial

"We are very happy with the HSD17B13 protein from OriGene and found great quality for our internal quality control. We’ve been very happy with your customer service as well and appreciated when there was a labeling mishap on one of the proteins OriGene promptly provided a new corrected protein sample."
