Select your optimal expression host and produce small quantities of non-GMP material for your development needs

Rapid Host Screen is a customized service to accelerate the selection of the optimal expression system for your protein of interest. Your molecule will be expressed in both our Mammalian GS Xceed® and Microbial XS® Expression Systems. This quick expression feasibility study will allow you to move with ease into small-scale non-GMP manufacturing with our Light Path™ Discovery Protein Production. The service provides you milligram to gram quantities of material to facilitate the selection and ranking of lead candidates from discovery phase manufacturability and safety assessments to preliminary in vivo functional studies.

Accelerate the selection of the optimal expression host system

As a host screen customer, your molecule will be expressed in both our Mammalian GS Xceed® and Microbial XS® Expression Systems at our process development centers. The use of production-ready cell lines provides future cost and time advantages when you are ready to manufacture batches for immunogenicity, safety, efficacy and other preclinical and phase I needs.

Light Path™ Host Screen provides rapid identification of your best option, in terms of protein quality, purity and yield, for successful protein expression. Quick expression system identification will allow you to move with ease into small-scale manufacturing.
