Hemagglutination - Wikipedia
网页Hemagglutination, or haemagglutination, is a specific form of agglutination that involves red blood cells (RBCs). It has two common uses in the laboratory: blood typing and the quantification of virus dilutions in a haemagglutination assay.
What is Hemagglutination? - News-Medical.net
网页2021年3月18日 · Hemagglutination is a reaction that causes clumping of red blood cells in presence of some enveloped viruses, such as the influenza virus. A glycoprotein on the viral...
Hemagglutination - an overview | ScienceDirect Topics
网页Hemagglutination is a classical method for viral diagnosis, but is still used for diagnosis of influenza virus today. One outstanding advantage of this method is that it does not require any equipment. Moreover, it is a robust and rapid diagnostic tool, but the sensitivity is somewhat limited.
Hemagglutinin - Wikipedia
网页Hemagglutinins are small proteins that extend from the surface of the virus membrane as spikes that are 135 Angstroms (Å) in length and 30-50 Å in diameter. [14] Each spike is composed of three identical monomer subunits, making the protein a homotrimer. These monomers are formed of two glycopeptides, HA1 and HA2, and linked by two disulphide ...

网页Hemagglutinins (HAs) are the receptor-binding and membrane fusion glycoproteins of influenza viruses. They recognize sialic acid–containing, cell-surface glycoconjugates as receptors but have limited affinity for them, and, as a consequence, virus attachment to cells requires their interaction with several virus HAs.
Hemagglutination - an overview | ScienceDirect Topics
网页Hemagglutinating viruses bind to sialic acid residues on the RBCs. A single virion can bind to several different RBCs, and an RBC can be bound by multiple virions to form a large network, or web, of cell and virus that is easily visualized.
Hemagglutination assay - Wikipedia
网页HA and HAI apply the process of hemagglutination, in which sialic acid receptors on the surface of red blood cells (RBCs) bind to the hemagglutinin glycoprotein found on the surface of influenza virus (and several other viruses) and create a network, or lattice structure, of interconnected RBCs and virus particles.

A haemagglutination test for rapid detection of antibodies to …
网页2021年3月29日 · Here we describe a quantitative Haemagglutination test (HAT) for the detection of antibodies to the receptor binding domain of the SARS-CoV-2 spike protein. The HAT has a sensitivity of 90% and specificity of 99% for detection of antibodies after a PCR diagnosed infection.
Hemagglutination - an overview | ScienceDirect Topics
网页Hemagglutination is a method used for diagnosing certain enveloped viruses, such as influenza viruses, by observing the clumping or agglutination of red blood cells caused by a substance called hemagglutinin (HA) present in the viruses.
