WebMar 5, 2024 · Direct fluorescent antibody (DFA) tests use a fluorescently labeled mAb to bind and illuminate a target antigen. DFA tests are particularly useful for the rapid diagnosis of bacterial diseases. For example, fluorescence-labeled antibodies against Streptococcus pyogenes (group A strep) can be used to obtain a diagnosis of strep throat from a ... WebWe propose a de novo glycan display that combines metabolic labeling and a glycan-caging strategy as a facile editing method for cell-surface glycans. This method enables the introduction of antigen glycans onto cancer cells to induce immune responses through antibody recruiting. The caging strategy …

WebMar 17, 2024 · Fluorescent Probe (Labeling antibodies) Takai et al. discovered a method for antigen detection inside tissue cells in which fluorescein-labeled antibodies were utilized as a histochemical stain. The antibody molecule can be conjugated with chemical compounds without disrupting its ability to react with its corresponding antigen. WebIndirect ELISA is a technique that uses a two-step process for detection, whereby a primary antibody specific for the antigen binds to the target, and a labeled secondary antibody against the host species of the primary antibody binds to the primary antibody for detection. As for direct ELISA assays, the antigen is immobilized to the surface of ...
WebTargeted radionuclide therapy (TRT) using targeting moieties labeled with α-particle-emitting radionuclides (α-TRT) is an intensely investigated treatment approach as the short range of α-particles allows effective treatment of local lesions and micrometastases.
