WebThe hemagglutination inhibition (HI) assay is used to titrate the antibody response to a viral infection. The HI assay takes advantage of some viruses' ability to hemagglutinate (bind) red blood cells, therefore forming a “lattice” … WebMar 18, 2024 · So the HAI titers were higher when using the same platform (VLPs) for the assay than using live virus . Thus, we applied ROC analysis to optimize the H7 VLP HAI …
WebSep 8, 2024 · HAI titers were taken as the reciprocal of the last dilution at which antibody was detected, and titers <10 were set to 5 for analysis. Participants were followed up with active surveillance from vaccination to the end of their study visit, which occurred between August 2009 and December 2010. WebDec 12, 2024 · An HAI titer of 1:40 was associated with substantially less than 50% protection against PCR-confirmed influenza virus infection …
WebMay 22, 2024 · Background: High hemagglutination inhibition (HAI) and neuraminidase inhibition (NAI) titers are generally associated with reduced influenza risk. While … Webthe HAI titer stands for haemagglutination inhibition, it is the reference test for influenza viruses. Be careful, the optical density obtained by ELISA is not an antibody titer, at best …
WebAntibody responses were defined as at least fourfold titer increases from baseline. Seroprotection was defined as a HAI titer ≥40. Enrolled CAR-T-cell recipients were vaccinated 14-29 days prior to (n=5) or 13-57 months following therapy (n=13), and the majority had hypogammaglobulinemia and cellular immunodeficiencies prevaccination. ...
