Hemagglutination Inhibition (HI) Assay of Influenza Viruses with Monoclonal Antibodies

open access: yesBio-Protocol, 2016
Heamagglutination is inhibited when antibodies are present because antibodies to the influenza virus will prevent attachment of the virus to red blood cells. The highest dilution of antibody that prevents hemagglutination is called the HI titer.

Hemagglutination Inhibition Assay [PDF]

open access: yes, 2020
The hemagglutination inhibition (HI) assay for influenza A virus has been used since the 1940s. The assay may be utilized to detect or quantify antibodies to influenza A viruses and can be used to characterize differences in antigenic reactivity between influenza isolates.

Pomegranate peel extract inhibits internalization and replication of the influenza virus: An in vitro study [PDF]

open access: yesAvicenna Journal of Phytomedicine, 2020
Objective: Influenza virus, which is associated with high level of morbidity and mortality, has been recently considered a public health concern; however, the methods of choice to control and treat it are limited. Our previous study showed anti-influenza

Development and Characterization of a Highly Sensitive NanoLuciferase-Based Immunoprecipitation System for the Detection of Anti-Influenza Virus HA Antibodies

open access: yesmSphere, 2021
Influenza virus HA-specific antibodies can be detected via the hemagglutination inhibition (HI) assay, the neutralization (NT) assay, and the enzyme-linked immunosorbent assay (ELISA).

Microneutralization assay titres correlate with protection against seasonal influenza H1N1 and H3N2 in children. [PDF]

open access: yesPLoS ONE, 2015
Although the microneutralization (MN) assay has been shown to be more sensitive than the hemagglutination inhibition (HAI) assay for the measurement of humoral immunity against influenza viruses, further evidence relating MN titres to protective efficacy

Seroprevalence of mycoplasmosis in broiler, layer, and native chickens in Giza, Egypt.

open access: yesPLoS ONE, 2021
We aimed to investigate Mycoplasma infections among chicken flocks (Ross, Lohmann and native) in Giza, Egypt, using serological tests, including the slide plate agglutination (SPA) test, hemagglutination inhibition (HI) test, and enzyme-linked ...

Hemagglutination Inhibition Assay for Gentamicin [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 1977
A rapid and simple hemagglutination inhibition test for measuring gentamicin concentrations in serum has been developed. Correlation coefficients for this assay with the radioimmunoassay and microbiological assay were r = 710 and r = 0.864, respectively.
