FAQ

What does GS Gene Expression System® platform support include, and how do I engage your team?

Lonza provides technical guidance to help developers apply the GS Gene Expression System® technology platform according to established platform principles. Support includes assistance with vector and host selection, expression workflow setup, evaluation of process parameters, and review of data to identify suitable optimization approaches. Our team also helps ensure alignment between early development decisions and later process requirements. You can reach our specialists through the “Speak to a GS system® platform expert” contact option on the technical support page.

Which common bottlenecks do you troubleshoot during GS Gene Expression System® technology platform onboarding and optimization?

Our team helps investigate areas that commonly influence expression outcomes, such as clone behaviour, vector configuration, media and feed strategies, and transitions between expression formats. We review user-generated data to identify potential contributing factors and outline practical steps that fit within the GS® platform framework. This approach supports consistent evaluation and informed decision making without implying performance guarantees.

What does XS Technologies® microbial expression platform optimization cover for the XS® Pichia system vs. the XS® E. coli system, and what inputs do you need from us?

XS Technologies® microbial expression platform optimization covers host selection aligned to molecule characteristics, assessment of expression or secretion behaviour, and guidance on establishing a reliable microbial workflow. Support follows the intended use of the XS® Pichia and XS® E. coli systems and focuses on identifying suitable development paths. To begin, we typically request information such as construct design, early expression data, and any known process constraints so we can provide tailored, non comparative technical recommendations.

Do you offer viral vector production technical support for early development, and which upstream parameters do you typically help optimize?

Yes. We offer technical support for applying Lonza’s viral vector tools during early development. Guidance may include reviewing parameters such as cell density, feed strategies, and transduction conditions. Our team helps identify potential sources of variability and outlines practical considerations for establishing processes suited to future scale up and manufacturing needs. This support is intended to inform development decisions without suggesting performance improvements relative to other technologies or service providers.

How is technical support tailored by modality and development stage?

Technical support is adapted to the needs of each modality and stage of development. Early stage guidance often focuses on expression strategy, host or vector selection, and establishing a workable process foundation. As programs progress, support may include considerations for scaleup, process consistency, regulatory alignment, and manufacturing suitability. The intent is to help developers apply Lonza technologies appropriately throughout their development pathway, without implying comparative advantages over alternatives.
