Abstract:
Objective:Quadrivalent influenza vaccines contain two lineages of type B virus, this study aimed to assess whether the result of single radial immunodiffusion (SRID) are accurate. The cross-interference of two type B hemagglutinins remains unknown.
Methods:We detected the vaccine samples developed by Jiangsu GDK Biological Technology Co., ltd by SRID.
Results:There was no significant difference between the HA content of antigen reagent, bulk sample and mixed sample of two B bulk within 10 to 40 μg/ml (P>0.05). Then each hemagglutinin B was diluted respectively by other three HA, 30 μg/ml, the other hemagglutinin B or phosphate buffer solution were measured within 10-160 μg/ml. Within 10-40 μg/ml, the HA content was proportional to the diameters of immunodiffusion (R2=0.998), while within the higher content range, a ternary linear regression equation fitted best (R2=0.999).
Conclusions:No cross-interference between B/Brisbane and B/Phuket was found in SRID within both detection ranges.
