Transient expression in high-titer CHO and HEK 293 with speed and cost-effectiveness, transitioning seamlessly to CHO stable expression
Protein Sciences: Early-Stage R&D Mammalian Platform
Program Features:
WuXi Biologics’ industry-leading Protein Sciences (PS) Department produces high-quality proteins and antibodies to meet your schedule and requirements. No project is too large or small. Our team of experts can support the preparation of the most complex proteins or provide one to thousands of standard antibodies and proteins for your diverse needs, including early-stage research, lead candidate screening, immunizations, in vivo studies, biochemical assays, and other research purposes. Projects can be structured by using a FTE or FFS model to meet your project needs. Our labs feature high-throughput expression and purification systems to maximize efficiency.
Projects start from customer- provided amino acid sequence (with codon optimization), DNA sequence, or plasmids Deliver high-quality proteins suitable for most in vitro and in vivo studies Provide comprehensive QC data Expi293/HEK293 are default systems for non-antibody reagent proteins (non therapeutics) Utilize our efficient, proprietary, high-yielding WuXian TM CHO-K1 for antibodies and other therapeutic proteins NS0 are also used

WuXian TM Express Platform
If you need more than a few grams of protein (e.g., developability studies), stable pool expression via the WuXian Express Platform is ideal. Our stable pool easily produces high-quantity and high-quality protein in 5-6 weeks in a shaker flask, wavebag or bioreactor.
