Beef fat with omega-3 acids: not bad for a start

Of the 14 calves, 11 died due to infections and improper development of internal organs. If infections can be attributed to insufficiently careful care, then developmental abnormalities could be the result of genetic modification.

Monoclonal antibodies in oncology

They are called monoclonal because they are produced by clone cells derived from a single progenitor cell. Monoclonal antibodies differ not only in their target target, but also in the way they fight cancer cells.

Alphamers direct antibodies to fight bacteria

Molecular beacons, or alphamers, bind to bacteria and attract antibodies against the carbohydrate alpha-gal to their surface, which contributes to the absorption and destruction of pathogens by cells of the immune system.
