Micro Developability: Early Assessment of Biologics

High-throughput, high-titer CHO production of miniproteins with high yields and low endotoxin levels, surpassing traditional E. coli production methods.

Early-Stage Developability Assessments for Lead Optimization · In Silico Analysis

WuXi Biologics’ Micro Developability Platform high-throughput (HTP), low-sample-consumption assays that can evaluate biophysical properties, PK, and manufacturability.

Developability is a Key Criteria
