Mammalian stable cell line generation

With our proprietary stable expression vector, we generate stable, high-yielding mammalian cell lines that give you high-level expression of recombinant proteins including recombinant antibodies and membrane proteins. Our expertise and in-house cloning reagents enables us to generate any stables cell lines in a more cost-effective and time-effective manner.

Case study – Generation of Mammalian Stable Cell Line

  • Workflow:

    • Protein A and Protein B were constructed into expression vector.
    • Co-Transfect into CHO cells..
    • Stable lines are selected with G-418 and MTX, then target gene is amplified with gradually increased MTX concentration.
    • Protein A and Protein B expression was detected with corresponding antibodies.
    • Gene function was determined by phospho-AKT antibody at the present of NRG.
  • Deliverables:

    Bioactive cytokine

  • 1. Target Protein Production in P. pastoris System

  • 2. Characterization of target protein product
