摘要
病毒滴度测定是生物制药行业重要的分析方法,广泛应用于病毒类生物制品的开发和生产、病毒清除灭活工艺验证、外源病毒检测等领域,以确保病毒类生物制剂的活性和有效性,以及生物制品的病毒安全性.因此,建立快速、简单且准确的病毒滴定检测方法尤为重要.总结了检测病毒滴度的传统方法、新兴以及改良方法的特点、原理及具体应用,并比较了各自的优缺点.一些新兴方法,如微滴式数字PCR、病毒定量毛细管电泳、化学发光ISH-PNA测定、激光力细胞学等改进了传统方法耗时耗力、重复性差、准确性低、结果主观性大的缺点,达到了快速、灵敏、自动化程度高、精密度高、结果更加稳健且客观的优点,但部分新方法仪器昂贵或者未广泛使用,需要根据实验目的选择合适的病毒滴定方法.
Abstract
Virus titration is an important analytical method in the biopharmaceutical industry,which is widely used in the devel-opment and production of viral biological products,the validation of virus clearance and inactivation processes,and the detec-tion of exogenous viruses to ensure the activity and effectiveness of viral biologics,as well as the viral safety of biological prod-ucts.It is important to establish a fast,simple,and accurate method for the detection of virus titration.This article summarized the characteristics,principles and specific applications of the traditional,emerging and improved methods for detecting viral ti-ter and compared their advantages and disadvantages.Some emerging methods,such as droplet digital PCR,viral quantitative capillary electrophoresis,in situ hybridization(ISH)assay with chemiluminescent detection,laser force cytology,etc.,have im-proved the shortcomings of traditional methods such as time-consuming and labor-intensive,poor repeatability,low accuracy,and large subjectivity of results,and have achieved the advantages of rapidity,sensitivity,high degree of automation,high preci-sion,and more robust and objective results.However,some new methods are expensive or not widely used,and it is necessary to select the appropriate virus titration method according to the experimental purpose.
