Rapid Protein Expression and Purification

Therapeutic recombinant protein drugs expressed in mammalian cells are closer to human natural protein in structure and function. Based on this, we launched the rapid protein preparation service. We have accumulated rich experience in protein preparation. It has successfully completed tens of thousands of protein preparations, covering various molecular types such as nanobodies, human or humanized IgG antibodies, cytokines and other types of recombinant proteins.

Service Highlights

1. Mammalian cell expression system, close to natural proteins

• In our rapid protein expression and purification services, mammalian cell expression system (CHO/HEK293) is used, and the recombinant protein obtained by the system has a biological active conformation similar to the natural proteins.

2. Multi-dimensional quality control system ensuring high quality

• The quality of the antigen and antibody proteins could be evaluated by multiple parameters, such as concentration, purity, molecular weight, aggregation, stability, safety, charge heterogeneity, sequence variant, structure analysis and binding or blocking bioactivity analysis.

3. Efficient delivery enabling the completion within 2 weeks

• It is an integrated service that includes plasmid construction, extraction, transient expression, protein purification and protein quality control, the whole process of which could be completed as fast as 2 weeks.

4. Personalized services providing flexible choices

• With 3 eukaryotic expression systems, several expression volumes, 2 transient methods, 2 purification tags and 8 quality control indexes provided, customers could obtain a high-precision customization based on the specific needs of the project by combining those five dimensions flexibly.
