Noninvasive Urine Biomarker Lateral Flow
2018-8-24 · In a competitive LFIA, a colloidal gold antibody conjugate that is specific for the biomarker is placed on the conjugation pad and a biomarker–protein conjugate is applied to test line. When urine is introduced to the sample pad, it migrates along the nitrocellulose membrane allowing for the colloidal gold antibody to competitively bind between the biomarker in the urine and the biomarker–BSA conjugate on the test …
