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.

Hemagglutinins (alternatively spelt haemagglutinin, from the Greek haima, 'blood' + Latin gluten, 'glue') are homotrimeric glycoproteins present on the protein capsids of viruses in the Paramyxoviridae and Orthomyxoviridae families. [1][2][3] Hemagglutinins are responsible for binding to receptors, sialic acid residues, on host cell membranes to...

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.

2022年12月13日 · Hemagglutination is a type of passive agglutination reaction. 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 infections. George Hirst was the person to discover hemagglutination tests. He was an American virologist.

2024年10月7日 · Hemagglutination assays are pivotal in various biological and medical fields, facilitating the study of viruses, bacteria, and blood typing. These assays leverage the natural ability of certain antigens to cause red blood cells to clump together, providing a versatile tool for diagnostics and research.

2024年5月17日 · Hemagglutination is a process that causes red blood cells, such as the influenza virus, to clump together in the presence of some enveloped viruses. Hemagglutinin, a glycoprotein on the viral surface, interacts with red blood cells, causing red blood cell clustering and the creation of a lattice.

Agglutination (clumping) is the oldest antibody-based reaction in medical diagnostics and is currently used in haematology and diagnostic microbiology. Specific agglutination was first described by the British physician Herbert Edward Durham and Austrian bacteriologist Max Von Gruber in 1896 and is known as the Gruber-Durham reaction.

hemagglutinin, any of a group of naturally occurring glycoproteins that cause red blood cells (erythrocytes) to agglutinate, or clump together. These substances are found in plants, invertebrates, and certain microorganisms.

HA is an immunological method of tittering virus based on their ability to bind with the RBCs surface receptor and results in agglutination of the virus. The test is performed by serially diluting the virus suspension and tittered with a consistent amount of red blood cells (s http://www.virapur.com/protocols/HA%20Protocol.pdf) [45].
