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
