Animal Antibody For COVID-19

Not only the antibodies of humans that have recovered from COVID-19 are being use as experimental treatment for the virus but also animals or animals's antibodies.

The antibodies of a horse and a llama are on the way to be use as experimental treatment for COVID-19.The antibodies of horse and llama can kick out or prevent the development of COVID-19.They produce an antibodies that could combat and kill the virus.

Horse and Llama has been undergone experimentation by the experts wherein the experts found out that these two animals have an antibodies that could easily remove or kill the virus and they will use their antibodies to treat people with COVID-19.

According to experts,llamas antibodies are the first antibodies that can or known to neutralize SARS-CoV2 which brought COVID-19.


"The researchers linked two copies of a special kind of antibody produced by llamas to create a new antibody that binds tightly to a key protein on the coronavirus that causes COVID-19. This protein, called the spike protein, allows the virus to break into host cells. Initial tests indicate that the antibody blocks viruses that display this spike protein from infecting cells in culture." (news utexas)

"Humans produce only one kind of antibody, made of two types of protein chains — heavy and light — that together form a Y shape. Heavy-chain proteins span the entire Y, while light-chain proteins touch only the Y’s arms. Llamas, on the other hand, produce two types of antibodies. One of those antibodies is similar in size and constitution to human antibodies. But the other is much smaller; it’s only about 25 percent the size of human antibodies. The llama’s antibody still forms a Y, but its arms are much shorter because it doesn’t have any light-chain proteins.This more diminutive antibody can access tinier pockets and crevices on spike proteins — the proteins that allow viruses like the novel coronavirus to break into host cells and infect us — that human antibodies cannot. That can make it more effective in neutralizing viruses.Llamas’ antibodies are also easily manipulated, said Dr. Xavier Saelens, a molecular virologist at Ghent University in Belgium and an author of the new study. They can be linked or fused with other antibodies, including human antibodies, and remain stable despite those manipulations." (nytimes)
