Abstract
Some embodiments of the disclosure provide a time-resolved fluorescent immunochromato-graphic test strip for detecting vancomycin as well as a preparation method and application thereof. In some embodiments, the test strip includes a bottom plate and a sample absorption pad. A fluorescent microsphere pad, a nitrocellulose membrane coated with a vancomycin-carrier protein conjugate, and an absorbent pad are sequentially overlapped and pasted on the bottom plate. The fluorescent microsphere pad is sprayed with a fluorescent microsphere-labeled vancomycin monoclonal antibody, and the vancomycin monoclonal antibody is prepared by using a vancomycin-bovine serum albumin conjugate as an immunogen.
