Ha assay
WebThe hemagglutination (HA) assay is a tool used to screen cell culture or amnioallantoic fluid harvested from embryonating chicken eggs for hemagglutinating agents, such as type A influenza. The HA assay is not an identification assay, as other agents also have hemagglutinating properties. Live and inactivated viruses are detected by the HA test. WebThe hemagglutination assay (HA) is a tool used to screen cell culture supernatant or amniotic-allantoic fluid harvested from embryonated chicken eggs for hemagglutinating agents, such as type A influenza. The HA is not an identification assay, as other agents also have hemagglutinating properties.

WebHyaluronic Acid AlphaScreen Assay (K-5800) The HA AlpahScreen Assay is a competitive, laser-excited, bead-based assay. The HA present in your sample competes with the Biotin-HA conjugated on donor beads for binding to the His-tag HA Detector conjugated on acceptor beads. Signal is generated when the donor and acceptor beads are within 200 nm. Webviruses and other viral respiratory pathogens. In addition, this assay could detect the H9 hemagglutinin (HA) gene from artificially reconstituted clinical samples spiked with H9N2 virus without any non-specific reactions. Therefore, this assay is highly sensitive and specific for H9 HA detection. The assay is useful both for diagnostic
