WatsonBio’s protein expression and purification platforms provide you high quality recombinant proteins used in biomedical and pharmaceutical research. We offer a number of recombinant protein services designed to meet your specific research goals, and multi protein expression systems, including bacteria, yeast, baculovirus infected insect cells, and mammalian cells. Our customized services give you the flexibility to start recombinant protein project at different stage, it can be from gene synthesis, plasmid generation, or from customer provided plasmids. With our extensive expertise and customized solution, we are able to work with you to ensure the efficient and high quality protein delivery, and scale-up production of biologics for research purposes.

Service Highlights

  • 4 protein expression systems – bacterial, yeast, insect and mammalian systems
  • Scale: 0.5mg-100g
  • Tags: His, GST, MBP, tag free, and other customized
  • Purification methods: Affinity chromatography, size-exclusion chromatography, desalting column, ion exchange, hydrophobic interaction
  • Purity: >75%, >85%, >95%
  • Project progress updates at each step
  • QC data includes SDS-PAGE & Western Blot (available for tagged proteins)
