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 for quantifying the relative concentration of viruses, bacteria, or antibodies. HA and HAI apply the … 展开
A general procedure for HA is as follows, a serial dilution of virus is prepared across the rows in a U or V- bottom shaped 96-well microtiter plate. The … 展开
HA and HI have the advantages that the assays are simple, use relatively inexpensive and available instruments and supplies, and provide results within a few hours. The assays are … 展开
Optimal and reliable results require controlling several variables, such as incubation times, red blood cell concentration, and type of red blood cell. Non-specific factors in the sample can lead to interference and incorrect titer values. For example, … 展开

在microbeonline.com上查看更多信息Hemagglutination occurs when measles viruses and red blood cells are mixed (see image a). But, if the serum of a person infected with measles virus is mixed with RBC and measles virus, there won’t be any agglutination of RBC. This phenomenon is known as hemagglutination inhibition. This arises because antibo…- 评论数: 10
