Washington [US]Jan. 1 (ANI / Sputnik): U.S. military scientists have identified a miniature antibody – a nanobody – produced by a llama that appears to work well in liquid or aerosol form, suggesting it could help protect a person from the novel coronavirus , the Defense Ministry said in a press release Thursday.
“Researchers have found that at least one of these nanobodies, called NIH-CoVnb-112, can be very effective at preventing infections or detecting viral particles by capturing SARS-CoV-2. [Covid-19] peak protein, ”the release said.
The nanobody deactivates the coronavirus by covering the teeth from the tip to the surface of the virus, deactivating the pathogen’s ability to infect the patient, according to researchers at the University of Health Sciences in Uniform Services cited in the communicated.

The llama was vaccinated five times in 28 days with a purified version of the spike protein to produce the nanobody, the statement said.
Nanobodies are a type of antibody about a tenth the weight of most human antibodies that are produced naturally by the immune system of camels, alpacas and llamas, the statement added.
Nanobodies are also more stable, less expensive to produce and easier to design than typical human antibodies, the release said. (ANI / Sputnik)
