New Delhi, Aug. 25 -- In a significant scientific development, researchers have discovered that Immunoglobulin M (IgM), the largest antibody in the human body, not only defends against bacterial toxins but also enhances the mechanical stability of proteins.

According to the Ministry of Science and Technology, a new property in the largest antibody goes on to change the existing understanding of antibodies from chemical keys that fit into microbial locks to mechanical engineers.

It further alters the physical properties of molecules to protect the human body, thus inspiring new therapies by designing antibodies that mechanically stiffen dangerous proteins and disarm them.

"Our immune system is armed with many types of antibodies, each w...
