WuXi AppTec triples peptide capacity

In response to growing demand worldwide, WuXi AppTec has commissioned two new peptide plants, one each at its Changzhou and Taixing sites in China. Both use digital operation systems with automated solvent delivery, in order to optimise production consistency, minimise human errors and reduce production cycle time.

This investment will increase the company’s total solid-phase peptide synthesis (SPPS) reactor volume to 32,000 litres. It also marks the official launch of Taixing as WuXi AppTec’s fifth API production sites.

Taixing covers an area of 28 hectares and houses nine plants, with a total of >1,000 m³, including a dedicated plant for API cleanrooms. It will make small molecules, peptides, oligonucleotides and conjugates. Once it is fully operational in 2025, WuXi AppTec’s total reactor volume for small molecule API and intermediates will exceed 4,000 m³.
