Case Studies

Supporting Gram-Level Therapeutic mAb Production Using Ultra-High-Titer Transient CHO Expression

Case Study 1: GramExpress Enables 1-100 g Recombinant Antibody Production in 3-4 Weeks

This case study highlights how the GramExpress workflow supports rapid, gram-scale monoclonal antibody production. By streamlining codon optimization, ultra-high-titer transient CHO expression, and customized multi-step purification, the platform delivers 1-100 g of recombinant antibodies in 3-4 weeks, with >95% purity verified by SEC-HPLC and <0.5 EU/mg endotoxin. Final products are further confirmed by LC-MS for molecular mass and structural integrity.

Optimized GramExpress workflow for large-scale monoclonal antibody production, integrating codon optimization, high-titer expression, and streamlined purification strategies to rapidly deliver gram-scale antibodies with high purity across multiple production scales.
