The selection of appropriate exposure conditions and irradiation doses is driven by a number of critical factors including: (1) the validation and control of the irradiation process itself; (2) the efficacy of the applied irradiation dose range for inactivating pathogens of interest; (3) determination and control of critical process attributes; (4) the potential impacts of these irradiation dose levels on the serum being irradiated; and finally, (5) the potential impact of irradiated serum on the medicinal product and the associated manufacturing process where serum is ultimately used. In order to increase awareness of these topics throughout the cell culture community, we have addressed these critical factors in the current review. Introduction This article is part of a series of papers that are being authored under the sponsorship of the International Serum Industry Association (ISIA) with the purpose of establishing best practices for processes employed in the gamma irradiation of animal serum. In the present article, we describe best practices for validating the efficacy of viral inactivation during gamma irradiation of serum. In general, these practices can be applied for validating pathogen reduction for other microbes. A survey of gamma irradiation efficacy for the inactivation of pathogens, especially viruses and mollicutes (mycoplasmas and acholeplasmas), in frozen serum will be presented. Finally, as will be explained further, a useful window of irradiation dosage must be established, not only in terms of fluency required for pathogen inactivation, but also keeping in mind that the desired performance characteristics of the material being irradiated must remain intact. The latter must be empirically evaluated both by serum manufacturers and end-users of the irradiated serum. Best practices for these evaluations have also been described. As will become apparent, there is a necessary trade-off between optimization of pathogen reduction by gamma irradiation and preservation of performance of the irradiated serum as a medium additive for cell culture applications. 1. Validation of the Efficacy of Gamma Irradiation for Viral Inactivation The main objectives of a validation study involving gamma irradiation of animal serum (or other animalderived liquid materials) are to: (1) establish the kinetics of virus inactivation in such matrices at various increasing irradiation doses; and (2) select a minimum irradiation dose at which adequate virus inactivation is achieved. An irradiation dose is expressed as fluency, in units of kiloGrays (kGy) or in units of megarads (MR), where 1 MR = 10 kGy. The term “fluency” incorporates both dose-rate and ti","PeriodicalId":88836,"journal":{"name":"Bioprocessing","volume":"15 1","pages":"12-21"},"PeriodicalIF":0.0,"publicationDate":"2016-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66230167","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}
