高效液相色谱在流感疫苗血凝素含量检测中的应用进展

Application progress of high performance liquid chromatography in detection of hemagglutinin content in influenza vaccine

目前,流感疫苗血凝素(hemagglutinin,HA)含量最常用的检测方法仍为单向免疫扩散法(single-radial immunodiffusion,SRID),但该方法所需标准品制备耗时较长,通常需要2~3个月。在大流行流感发生初期无法获得标准参考品时,如何精确定量分析HA,一直是HA含量检测面临的难题。高效液相色谱(high performance liquid chromatography,HPLC)具有快速、灵敏度高、重复性较好以及准确性高的特点,利用不同的分离原理可快速测定HA含量,在流感疫苗HA含量检测方面已得到很多应用。本文对HPLC在流感疫苗HA含量检测中应用的研究进展作一综述。

At present,the most commonly used method for detecting hemagglutinin(HA)content in influenza vaccines is still single-radial immunodiffusion(SRID). However,the preparation of standards required by this method takes a long time,usually 2 ~ 3 months. Therefore,how to quantitatively analyze HA accurately has always been a difficult problem in the detection of HA content in the situation that reference products can not be obtained at the early stage of the pandemic influenza. High performance liquid chromatography(HPLC)has its own characteristics of rapidity,high sensitivity,good repeatability and high accuracy,which can rapidly determine HA content by using different separation principles and has been widely used in the detection of HA content in influenza vaccine. This paper reviewed the research progress of the application of HPLC in the determination of HA content in influenza vaccine.
