目的：建立能准确测定四价流感病毒裂解疫苗中B型血凝素含量（单向免疫扩散法，SRD）的检测方法。方法采用双价抗原参考品SRD法对四价流感病毒裂解疫苗中两种B型血凝素含量进行测定。将B1与B2抗原参考品按质量浓度1∶1混合制备为双价抗原参考品，双价抗原和待检样品与10％裂解剂按9∶1比例裂解30 min，分别加入到含有抗血清参考品的1．5％琼脂糖凝胶板上，每孔10μL，置20～25℃放置18～24 h，经干燥、染色、脱色，测量结果。验证双价抗原SRD法的重复性和准确性。结果双价抗原SRD法测定的血凝素含量平均值比单价抗原SRD法更接近理论配制值，故双价抗原SRD法比单价抗原SRD法能更能准确检测QIV中两种B型血凝素含量，经验证双价抗原SRD法的重复性及准确性良好。结论双价抗原SRD法提高了四价流感病毒裂解疫苗B型血凝素含量检测的准确性，为精确测定四价流感病毒裂解疫苗中B型血凝素含量提供了有效的方法和数据支持。

Objective To establish the HA content determination method ( SRD) of type B for quadrivalent influenza vac-cine(QIV).Methods The determination of hemagglutinin (HA) content for two types of B strains in QIV was performed by using of a bivalent reference antigen .Prepare bivalent reference antigen with mix B 1 and B2 reference antigen according to 1 ∶1(C/C).Split bivalent reference antigen and samples with 10%split solution in 9 ∶1 ratio for 30 min, load 10μL/hole samples to 1.5%agarose gel that with a enough specific reference antiserum .Then put that gel at 20-25 ℃for 18~24 hours, then drying, staining, destaining and measure he result .Validate the repeatability and accuracy of the bivalent reference SRD method .Results The mean is more close to theoretical value by using bivalent reference than using mono-valent reference to determine B type of QIV .So it is more accurate by using bivalent reference than using monovalent refen-rence to test HA of type B .The accuracy and repeatability of this method is satisfied demonstrated by validating .Conclu-sion The developed method could improve accuracy in determination of type B strains in QIV .It approve effective method and supported data to determinate HA content of type B for QIV .
