haemagglutination BrE

Hemagglutination is the process by which red blood cells agglutinate.

Therefore hemagglutination is inhibited when antibodies are present at a sufficient concentration.

The hemagglutination assay also allowed researchers to determine how much antibody was in a person's serum.

A variety of methods exist to adsorb these antibodies from the test sample before hemagglutination.

Many traditional serological tests such as hemagglutination or complement fixation employ this principle.

Any antibodies present would bind to viruses and prevent the hemagglutination reaction that would otherwise take place.

It has a higher sensitivity than other tests like hemagglutination and many commercial Enzyme immunoassay without compromising specificity.

The titer of a hemagglutination assay is determined by the last viable "lattice" structure found.

This process is called hemagglutination or haemagglutination.

The agglutin involved in hemagglutination is called hemagglutinin.

It causes direct hemagglutination.

He used that observation to develop a method, the hemagglutination assay, that allowed him to estimate the amount of virus present in a sample.

Burnet made significant contributions to influenza research; he developed techniques to grow and study the virus, including hemagglutination assays.

Hirst developed this reaction into the hemagglutination assay, which allows the amount of virus in the sample to be measured.

Hemagglutination, a clumping of red blood cells in response to the presence of antibodies in the blood, may also occur.

Cells determined to be non-self are usually recognized by the immune system as foreign, causing an immune response, such as hemagglutination.

Besides discovering the hemagglutination assay, Dr. Hirst studied the basic biology of viruses.

However, antibody testing was performed by using a hemagglutination assay, which tends to underestimate protection and cannot directly be compared with antibody concentration.

The hemagglutination assay (HA) is a common non-fluorescence protein quantification assay specific for influenza.

Other tests include various fluorescence assays, indirect hemagglutination, (PCR) and latex agglutination.

Hemagglutination provided a convenient method of diagnosing influenza in the laboratory, which had previously been performed by cultivating the virus in ferrets.

Hemagglutination, or haemagglutination, is a specific form of agglutination that involves red blood cells (RBCs).

These two glycoproteins are the targets of numerous serologic reactions and tests including neutralization and hemagglutination inhibition.

This is the basis of hemagglutination when viruses are mixed with blood cells, and entry of the virus into cells of the upper respiratory tract.

The hemagglutination inhibition assay is a common variation of the HA assay used to measure flu-specific antibody levels in blood serum.

This domain is suggested to be a carbohydrate-dependent haemagglutination activity site.

The haemagglutination and haemolytic activity are started by binding carbohydrates.

The haemagglutination inhibition test can be used to establish the strain of coronavirus.

This process is called hemagglutination or haemagglutination.

There is also a serological test for melioidosis (indirect haemagglutination), but this is not commercially available in most countries.

Attachment proteins with neither haemagglutination nor neuraminidase activity are designated G (glycoprotein).

Serological testing via virus neutralisation and haemagglutination inhibition testing can be performed to diagnose the disease.

Hemagglutination, or haemagglutination, is a specific form of agglutination that involves red blood cells (RBCs).

Diagnosis of the viral infection involves electron microscopy, ELISA or haemagglutination inhibition.

Specifically, Egg Drop Syndrome can be diagnosed by hemagglutinin inhibition and the virus causes haemagglutination in chickens and ducks.

Bacterial culture, immunofluorescent antibody testing (IFAT), complement fixation test and haemagglutination can all be used to confirm the diagnosis.

In 1941-42, George Hirst (1909-94) developed assays based on haemagglutination to quantify a wide range of viruses as well as virus-specific antibodies in serum.

These possess both haemagglutination and neuraminidase activity, which cleaves sialic acid on the cell surface, preventing viral particles from reattaching to previously infected cells.

Electron microscopy, PCR, complement fixation, antibody fluorescence, neutralization test and haemagglutination can be used to identify the virus in tissues or secretions.

Proteins are designated H (hemagglutinin) for morbilliviruses as they possess haemagglutination activity, observed as an ability to cause red blood cells to clump in laboratory tests.

The hemagglutination assay (or haemagglutination assay; HA) is a method of quantification for viruses or bacteria by hemagglutination.

The mushroom produces the Laetiporus sulphureus lectin (LSL) which has haemolytic and haemagglutination activities.

ABO blood group state was found by standard haemagglutination techniques with monoclonal reagents and red cell suspensions prepared by the Scottish National Blood Transfusion Service.

Immunofluorescence (IF), PCR, haemagglutination, ELISA and electron microscopy can be used to identify and diagnose the virus.

In molecular biology, the haemagglutination activity domain is a conserved protein domain found near the N terminus of a number of large, repetitive bacterial proteins, including many proteins of over 2500 amino acids.

Standard haemagglutination inhibition techniques with diluted human anti-A, anti-B, and anti-H (extracted from the lectin Ulex europaeus ) were applied with saliva at dilutions up to one in 16.

Antibodies to IBV may be detected by indirect immunofluorescent antibody test, ELISA and Haemagglutination inhibition (haemagglutinating IBV produced after enzymatic treatment by phospholipase C).
