The hemagglutination assay or haemagglutination assay (HA) and the hemagglutination inhibition assay (HI or HAI) were developed in 1941–42 by American virologist George Hirst as methods …

Apr 7, 2023 · As a vital tool in virology and immunology research, the HAI assay provides invaluable insights into the presence and concentration of influenza virus-neutralizing …

The basis of the HAI assay is that antibodies to that particular virus (for example; measles virus) will prevent the attachment of the virus to RBC. Therefore hemagglutination is inhibited when …

In this study, we standardized HAI assay materials, methods, and interpretive criteria across five geographically dispersed laboratories of a multidisciplinary influenza research network and …

Hemagglutination inhibition (HAI) assay are commonly used in typing and subtyping of influenza viruses (Hirst, 1942). Other agglutination assays include latex agglutination (LA) systems …

Oct 12, 2023 · The assay can aid in the diagnosis and monitoring of viral infections by evaluating the agglutination reaction between the virus and red blood cells. HA is also used to detect …

Hemagglutination inhibition (HAI) antibody titers to seasonal influenza strains are important surrogates for vaccine-elicited protection. However, HAI assays can be variable across labs, …

Dec 13, 2022 · Hemagglutination assay (HA) is a type of immunoassay in which erythrocytes are used as carrier particles and are commonly preferred for serological diagnosis of various …

The hemagglutination inhibition assay (HAI) is widely used to evaluate vaccine-induced antibody responses as well as to antigenically characterize influenza viruses. The results of an HAI …

Empower your antiviral research with Creative Diagnostics' Hemagglutination Inhibition Assay (HAI). Our specialized assay offers precise insights into viral inhibition, making it a valuable …
