Because it is possible to differentiate between the individual classes of immunoglobulins by enzyme immunoassay, more precise statement about the status of patients can be made with these tests, than other tests like the Haemagglutination Inhibition assay or Complement fixation test.
Agglutinating virus in harvested allantoic fluid was identified by spot agglutination assay using 10% chicken red blood cells (RBCs) and the identity of the virus was determined by NDV specific antisera through standard haemagglutination inhibition (HI) assay.
InDevR is currently responsible for the manufacturing and marketing of Cypher One, which is an automated haemagglutination analyser that is utilised by biopharmaceutical vaccine manufacturers and veterinary diagnostic labs.
Antibody response to sheep red blood cells (SRBCs): In control (PBS) and administered (vitamin-E; beta-glucans) chickens, humoral immune response was detected by haemagglutination test in terms of antibody titers (geomean titers; GMT) to sheep RBCs on day 7th and 14th after first and second injections of SRBCs.
Comparison of cell culture-grown JC virus (primary human fetal glial cells and the JCI cell line) and recombinant JCV VP1 as antigen for the detection of anti-JCV antibody by haemagglutination inhibition.
