Purdue University researchers now have developed an innovative, paper-based diagnostic test for rapidly detecting avian ...

The LAMP assay specifically targets the H5 hemagglutinin gene of the avian influenza virus. This assay offers important advantages over traditional diagnostic methods, Kamel noted. It detects the ...

Our results indicated that this combinational assay showed high sensitivity (100%) and specificity (95%) when compared with hemagglutinin inhibition (HI) assay. Fifty-one sera samples (34.2%) ...

The single radial immunodiffusion (SIRD) assay has been adopted internationally for the assay of influenza vaccines to estimate their HA antigen content. To measure SRID reaction zones, the virology ...

The refolding of the prototypic fusogenic protein hemagglutinin (HA) at the pH of fusion is considered to be a concerted and irreversible discharge of a loaded spring, with no distinct intermediates ...

Here, we present an integrative structural-modeling and physics-based computational assay that reveals the sialic acid association rate constants ... the hemagglutinin (HA), neuraminidase (NA) active, ...

This assay utilizes surface proteins of various viruses, such as hemagglutinin (HA) of the influenza virus, to agglutinate red blood cells (RBCs). The reaction of viral hemagglutinin with RBCs creates ...

In addition, the total assay time is less than 2 hours, with no need for deformulation or extraction, resulting in the desired cost and speed efficiency for mRNA CQA testing.
