Abstract:
OBJECTIVEThrough observing the morphological changes of the prepared influenza viruses (H1N1) treated with the different concentration of Nonidet P-40 solutions and added with antibody against the influenza virus using transmission electron microscopy (TEM), to explore the principle of application of the internal antibody for immunoassay of influenza virus.
METHODSThrough treating the virus samples with serial diluted Nonidet P-40 solutions from 0.01% to 0.2% and/or not adding antibody against the influenza virus, then investigating the samples by TEM to obtain the morphological changes of the virions.
RESULTSThe serial images show that the denudation degree of the virions is proportional with the rise of NP-40 concentration, and partly denuded virion image appeared at 0.1% NP-40 treatment, also under this condition no influence was observed on antibody binding to the virus.
CONCLUSIONThis work demonstrated the interaction between influenza virion and its antibody under nonionic surfactants existing, which supports the advantages of sample preparation for immunoassay enveloped virus using internal antibody theoretically.
