@tilscience: Alpacas are solving your cat allergy and not in the way you might think. Alpacas, along with a few other animals, produce something that no other animals do - something called "nanobodies," which are antibodies but super tiny yet just as effective. Nanobodies can squeeze into places that our normal antibodies can’t. So, these scientists figured out how to reverse-engineer nano bodies to break down Fel d1, the main allergen in cat saliva. The results are pretty impressive, 98% efficacy, with people reporting they can stay in homes with cats without symptoms. What’s really exciting is that nanobody technology is being developed for other medical purposes like COVID and cancer treatment. It's one of those solutions that came from a pretty unexpected place. #Science #EduTok #DidYouKnow #allergies #catsoftiktok
