Delivery of 100 mg mAb within a 3-week timeframe

  • Antibody properties:

    • Human IgG4, Human Kappa Light Chain​

  • Strategy: 

    • Gene synthesis of codon-optimized VH/VL regions

    • Cloning VH/VL sequences into our pre-synthesized Fc vector 

    • Co-transfection with two constructs into Expi293 expression system

    • Purification by MabSelect SuRe LX and Superdex SEC

    • Endotoxin removal

  • Deliverables: 

    • 100mg purified antibody >SEC-HPLC 98% purity, endotoxin < 0.1EU/mg

    • Turnaround time: 3 weeks


Pictured below is the SEC-HPLC (>98%) data.


Endotoxicity data, demonstrating an endotoxin level <0.1EU/mg.

Pictured below are the SDS-PAGE analysis results.

  • Strategy: 

    • A VH and a VL domain are connected together via a linker peptide

    • ScFv expression in Expi 293 expression system with VH-(GGGGS)3-VL-6x His

  • Deliverables: 

    • Purified antibody

    • SEC-HPLC >99% purity

Pictured below are the SDS-PAGE analysis results:
