At Novoprotein, we carefully design a unique purification strategy for each individual protein. This enables us to purify most untagged recombinant proteins within three-steps: capture, intermediate step, and polish. Our strategy ensures a high recovery rate. For tagged proteins, our two-step purification method can achieve greater than 95% purity in most cases.
Why choose us?
- Multiple purification systems in a temperature controlled environment
- Extensive collection of chromatography media
- Creative configurations of chromatography columns tailored to each protein
- Vigorous quality assurance programs to ensure the required quality and reproducibility
- Production capacity of up to 30 grams
- Greater than 98% purity
- Strong trouble shooting and difficult protein handling experience
