With the rapid development of biopharmaceutical industry, high-throughput miniature bioreactor systems have been widely used in recent years.The high-throughput miniature bioreactor system has the advantages of small size, high-throughput and good scalability, as well as the capability of online anal. and feedback control.At present, it is mainly applied in cell line selection, process optimization and process characterization.High-throughput technologies combining with exptl. design can shorten the product development timelines significantly, improve the process robustness and product quality control, and accelerate the delivery of projects into clin. and com. phase.This review mainly describes several common high-throughput miniature bioreactor systems and describes their applications in the biopharmaceutical industry, using Ambr system as an example.
