| Description | Antibody labeling with a signal-providing tag (e.g. an enzyme, chromophore, fluorophore, metal chelate, radioisotope, etc.) is a key procedure in bioanalytical techniques such an enzyme-linked immunosorbent assay, western blot, or immunohistochemical analysis. The process may be laborious, impair the activity, and time-consuming. Concisely, in this work, an elegant method of rapid and effective antibody labeling by quantum dots was developed taking advantage of partial reduction of antibody structure and UV-induced quantum dot formation. Zinc and cadmium with the thiol group of the antibody as capping agents stabilizing the fluorescent nanoparticle while the biorecognition capabilities were maintained. The ZnCd/S quantum dots creation has to prosper detected with capillary electrophoresis (CE) and laser ablation ICP- MS (LA- ICP- MS). |
