Medical search. Wikipedia Anti-idiotypic activity or inhibition of this activity was quantitat-ed by a continuous-flow automated hemagglutination sys-tem employing the Technicon AutoAnalyzer (13). Equine Influenza Virus H3N8 Hemagglutination Inhibition Test Data The hemagglutination inhibition (HI) assay is the test of choice for serological diagnosis of influenza infections in animals. Hemagglutination (HA) and hemagglutination inhibition (HAI) functional assays remain important instruments of analysis of virus-cell interaction and protecting efficacy of virus-specific antibodies and sera. hemagglutination inhibition test, etc ; Orthomyxoviridae; ferrets; hemagglutination; human influenza; monitoring; rats; statistical analysis; Show all 8 Subjects Abstract:. Automated Imaging and Analysis of the Hemagglutination Inhibition Assay ... The hemagglutination titer is the highest dilution of serum that completely inhibits hemagglutination by a standardized viral preparation. The results of an HAI assay are based on an endpoint titration where the titers are generally manually interpreted and recorded by a well-trained expert. In 1960 Gemzell and Leif Wide presented a pregnancy test based on in-vitro hemagglutination inhibition, a first step away from .This test initiated a series of improvements in pregnancy testing leading to the contemporary at-home testing.Gemzell was a . Results showed that such prepared antigens are highly specific to the serum samples derived from DTMUV-infected animals. THE isolation of rubella virus1 , 2 in 1961 opened a period of remarkable progress in studies of the virus,3 the disease4 and, recently, experimental vaccines for preventing the disease.5 , 6 Compa. Surface-assisted hemagglutination and hemagglutination inhibition assays Hemagglutination inhibition (HI or HAI) is used to determine relative concentrations of viruses, bacteria, or antibodies invented by American virologist George Hearst in 1941. The mission of the refereed section of the journal is to disseminate high-quality, peer-reviewed information on animal biology, technology, facility operations, management, and compliance as relevant to the AALAS membership. Comparative Study on the Anticancer Drug Potential of a Lectin Purified ... Therefore hemagglutination is inhibited when antibodies are present. PLOS ONE: Hemagglutination inhibition test
