Comparability of poliovirus neutralizing antibody tests
Biologicals, 1992A serology panel was used to assess the comparability of results of poliovirus neutralizing antibody assays. Five laboratories from three countries provided results with seven in-house methods. A high degree of within-laboratory reproducibility was seen for all laboratories and methods, with 94% of results for repeat titrations within plus or minus one

Neutralization Tests with Certain Neurotropic Viruses
The Journal of Immunology, 1944Abstract The relative lack of sensitivity of intracerebral virus-neutralization tests in mice, and their consequent limitations when applied to the investigation of certain epidemiologic or immunologic problems, is generally recognized. Inasmuch as the ability to detect or quantitate neutralizing antibodies in a serum is ...

A Microeconomic Test of Money Neutrality
The Review of Economics and Statistics, 1984Conventional empirical studies of money neutrality have focussed on the response of aggregate economic measures to anticipated and unanticipated money supply shocks. The present paper uses data from the U.S. pork industry to test for money neutrality at the microeconomic level.

AGAINST the vast panorama of the second World War the destinies of the northern Kingdom of Sweden appear as not much more than a tiny detail, but it is perhaps a detail of some peculiar configuration and interest. In September I939 twenty European States declared their neutrality.

European Journal of Political Economy, 1989
Abstract The paper is concerned with tests for Granger causality and for cointegration between (log) money and (log) output in Germany. Augmented Dickey—Fuller tests show that only second differences of both variables are stationary and only first differences (and not levels) are cointegrated. Furthermore it is shown that there is most times feedback

Journal of Applied Mechanics, 1956
Abstract Three tests have been carried out using hollow tubes of alpha brass subjected to combined torsion and internal pressure. An initial torque was applied sufficient to cause plastic deformation, and then the torque was decreased and the internal pressure increased to keep the octahedral shear stress constant in two tests and the ...

Modified radial-plaque-neutralization test for demonstration of enterovirus neutralizing antibodies
Archives of Virology, 1980A simple radial method based on the formerly described paper disc technique was developed for demonstration of neutralizing antibodies to enteroviruses with plaque forming ability. Sera administered by 5 microliter wire-loops to wells cut into the agar overlay of virus infected cell monolayers produced radial neutralization zones with a size directly ...

Neutralization Assay for Chikungunya Virus Infection: Plaque Reduction Neutralization Test
2016Neutralization assay is a technique that detects and quantifies neutralizing antibody in serum samples by calculating the percentage of reduction of virus activity, as the concentration of virus used is usually constant. Neutralizing antibody titer is conventionally determined by calculating the percentage reduction in total virus infectivity by ...

Measles Foci Reduction Neutralization Test (FRNT)
The plaque reduction neutralization test (PRNT) and the enzyme-linked immunosorbent assay (ELISA) are both widely used to assess immunity to infectious diseases such as measles, but they use two different measurement principles: ELISA measures the ability of antibodies to bind to virus components, while the PRNT detects the aptitude of antibodies to ...Sabine Santibanez, Annette Mankertz
