In vitro anti-reovirus activity of kuraridin isolated from Sophora flavescens against viral replication and hemagglutination

Journal of Pharmacological Sciences, 2015
In this study, we evaluated the anti-reovirus activity of kuraridin isolated from the roots of Sophora flavescens. In particular, we focused on whether this property is attributable to direct inhibition of reovirus attachment and/or inhibition of viral ...

Transplacental Chikungunya Virus Antibody Kinetics, Thailand

Emerging Infectious Diseases, 2006
Antibodies to chikungunya virus were detected by hemagglutination-inhibition assay in 33.6% of 2,000 infants' cord sera at delivery. Follow-up of 24 seropositive infants showed that the half-life of antibody persistence was 35.5 days.

An Optimized Hemagglutination Inhibition (HI) Assay to Quantify Influenza-specific Antibody Titers [PDF]

Journal of Visualized Experiments, 2017
Antibody titers are commonly used as surrogate markers for serological protection against influenza and other pathogens. Detailed knowledge of antibody production pre- and post-vaccination is required to understand vaccine-induced immunity. This article describes a reliable point-by-point protocol to determine influenza-specific antibody titers.
