Test of the neutrality hypothesis

Annals of Human Genetics, 1976
*Note. Dr Price died unexpectedly in January 1976 while he was working on the Kimura neutral gene hypothesis. He had been investigating methods of programming and using a significance teat, due to W. J. Ewens (1972), and had been applying them to the date on enzyme polymorphisms collected in the Galton Laboratory.

Testing for neutralizing antibodies

British Journal of Neuroscience Nursing, 2007
Interferon-beta drugs for multiple sclerosis sometimes give rise to immune proteins that neutralize their effects. Nicola O'Connell and Bronwen Roper look at testing for these neutralizing antibodies

Platelet Neutralization Test

2013
The platelet neutralization test is used in the laboratorvy diagnosis of the lupus anticoagulant (Laffan and Manning, Dacie and Lewis practical haematology. Churchill Livingstone, Philadelphia, PA, pp 445-446, 2006). The lupus anticoagulant typically causes prolongation of phospholipid-dependent coagulation tests such as APTT, DRVVT, etc.

Standardization of Poliovirus Neutralizing Antibody Tests

Clinical Infectious Diseases, 1984
Recently the Forum for Advancement of Immunization Research sponsored a Collaborative Study on Poliovirus Antibody Titration. Twenty laboratories from 12 countries participated. There were considerable differences in detail of test performance and test results among laboratories.

Testing short-run neutrality

Journal of Monetary Economics, 1986
Abstract This paper derives and implements a robust test of the short-run neutrality of anticipated policy that is valid when the information set used to form expectations is incorrectly specified and the effect of unanticipated policy on deviations of output from the natural rate varies over time.

Neutralization Assay for SARS-CoV-2 Infection: Plaque Reduction Neutralization Test

2022
Neutralization assays are often used as part of research and diagnostics to detect neutralizing antibodies and to determine a possible protective antibody titer after infection or vaccination. Here we describe a conventional plaque reduction neutralization test (PRNT) to check the presence of antibodies against SARS-CoV-2 in patient samples (serum or ...

Comparability of poliovirus neutralizing antibody tests

Biologicals, 1992
A 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, 1944
Abstract 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, 1984
Conventional 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.
