Abstract
A Raman spectroscopy integrated perfusion cell culture system for monitoring and auto-controlling perfusion cell culture, comprising: a bioreactor, comprising: (1) an interior chamber for receiving a cell culture, (2) a port for feeding nutrient materials from a feed reservoir into the interior chamber, (3) a port for auto-bleeding from the interior chamber, and (4) a port for continuously harvesting materials from the interior chamber with the help of a cell retention system; a Raman analyzer, comprising (i) one or more Raman probes which are immersed into the bioreactor and is configured to collect Raman spectrum in the bioreactor, and (ii) a host computer which is configured to receive the Raman spectrum collected and transferred by the Raman probe and turn it into values; and a controller in communication with the Raman analyzer, the feed reservoir and an auto-bleeding device, the controller being configured to receive the values from the Raman analyzer and compare them with preset parameters, based on results from comparing, the controller further being configured to control the feed reservoir for adjusting the feeding rate of nutrient materials into the bioreactor, and being configured to control the auto-bleeding device for auto-bleeding materials from the bioreactor. A process for monitoring and auto-controlling perfusion cell culture by using this system.
