Broadly Neutralizing Antibody Cocktails Targeting Nipah Virus and Hendra Virus Fusion Glycoproteins
Hendra virus (HeV) and Nipah virus (NiV) are types of Henipaviruses (HNVs) that originated in bats and can infect the human respiratory system with detrimental consequences. As enveloped, single-stranded RNA viruses, HeV and NiV use attachment (G) and fusion (F) glycoproteins on the envelope membrane to enter host cells. So far, there are no approved therapeutics or vaccines to combat the viruses in humans.

First Immunoassay for Measuring Isoaspartate in Human Serum Albumin
The ongoing pandemic has reinforced the need for in vitro diagnostics to globally surveille emerging pathogens and provide better medical care. In particular, immunoassays are favoured due to their affordability, ease, and speed. Nevertheless, the combination of rapidly evolving pathogens, and more complex diseases resulting from increasing life expectancy worldwide require more sensitive and specific immunoassays in the nick of time. To increase sensitivity, immunoassay development can benefit from exploiting industry-leading technologies such as de novo protein sequencing.
