Lonza describes GS-ORI-GO as an evolution of the GS Xceed workflow that adds a high-strength product-expression promoter plus tighter glutamine synthetase expression control (Lonza’s GS-ORI-GO white paper page, 2026-10-08). The host cell stays the same; what moves is where selection pressure is applied.
The headline is direct progression from bulk pools to clonal cell lines, removing the need for enriched pools and methionine sulfoximine (MSX) selection, kwa nke Lonza 3 June 2026 media advisory. The mechanism behind that stringency is structural: CHOK1SV GS-KO cells lack endogenous glutamine synthetase, so only cells integrating the vector survive in glutamine-free media (Lonza’s GS expression system overview).
Lonza reports lead-clone titers higher than 11 g/L and more than a 30% mmụba na titers gafee mAbs, bispecific na protein fusion (nke Lonza 3 June 2026 media advisory), n'akụkụ 97% nnukwu ọdọ mmiri kwụsie ike na ukwuu karịa 90% mmepụta oyiri kwụsie ike (Akaụntụ Lonza nke nkwụnye ego nzọụkwụ).
