Antibodies have always been the ultimate fighters of the immune system because of their long life. Depending on the disease, some antibodies can hang out in our bloodstream for years after infection. This type of protection keeps us from getting sick again and allows us to do germy-yet-fun things like travel across the world in an enclosed metal tube (aka, airplane). Our gold-plated antibody necklace is us giving these awesome proteins a figurative gold star. Purchase it for yourself or gift it to an immunologist, a microbiologist, a survivor, or a starry-eyed pre-med student.
