Abstract
Ag—Fe3O4 immunomagnetic microsphere contains poly-D-lysine modified on the surface and S100β and/or MBP antibody linked by an amide bond. The Ag—Fe3O4 immunomagnetic microsphere can specifically capturing peripheral nerve tissue-derived exosomes. When the microsphere is used to extract nerve tissue-derived exosomes, the extraction yield of exosomes per unit volume of nerve tissue is high, and the nerve specificity is strong.
