To establish a method for measurement of the neutralizing activity of a monoclonal antibody against the rabies virus. Twenty-four rabies street virus-positive samples were isolated by the mouse inoculation test. Isolated rabies street viruses were cultured and the virus titer tested in N2A cells. We established a rabies street virus bank with viruses that could adapt to the growth of N2A cells with a high titer. Then repeatability was evaluated after three detections of the TRN006 monoclonal antibody. Of the 24 positive samples,15 strains of the virus could adapt to N2A cells and form fluorescent foci in cells.Finally,10 strains with a high titer were selected for the rabies street virus bank, which covered nine Provinces of China and four Chinese lineages. Three lineages were used for the neutralization test for the monoclonal antibody, and the Student’s t-test showed that it had good repeatability.
