However, several relevant parameters are not measured in standard bioreactor systems. Near-infrared spectroscopy (NIRS) is one promising technology capable of becoming the missing link in sensor technology. This review gives an overview of the technological principles and the technological progress. A broad range of possible applications is presented, forming in its entirety a valuable toolbox for process risk mitigation. Recent applications of NIRS in upstream bioprocesses are discussed. Moreover, the review includes regulatory aspects in implementation, calibration and validation of NIRS instrumentation and models.","PeriodicalId":90285,"journal":{"name":"Pharmaceutical bioprocessing","volume":"3 1","pages":"153-172"},"PeriodicalIF":0.0,"publicationDate":"2015-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4155/PBP.15.1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70350323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Affinity chromatography is usually applied during large-scale protein purification; it involves affinity ligands of biological or synthetic origin. The high productivity that is currently achieved during upstream processing is placing an increasing burden on the downstream production phase which suffers from limited capacities. Consequently, while genetic engineering is helping to increase the stability and capacity of natural ligands, in silico approaches combined with combinatorial chemistry may be used to implement economical purification strategies based on synthetic ligands for the improvement of downstream processing and biomanufacturing.","PeriodicalId":90285,"journal":{"name":"Pharmaceutical bioprocessing","volume":"3 1","pages":"139-152"},"PeriodicalIF":0.0,"publicationDate":"2015-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4155/PBP.14.60","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70348975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This established the system as a scale-down model for process development and characterization of large-scale industrial processes.

Continuous manufacturing methods can provide increased product quality and process control, and reduced operating costs. Continuous biomanufacturing (CB) additionally promises reduced classified area extent, personnel requirements and operating steps. The benefits of SU CB include heightened processing parameter consistency and increased process flexibility. Perfusion culture (PC) is supported by many specialized SU and hybrid bioreactors. These and many accessory perfusion-enabling technologies are the main way of implementing upstream CB. Valuable features provided by PC include reduced product reactor-residency and increased reactor-volumetric productivity.
