Fluorescent staining or probing
WebDec 15, 2024 · Fluorochrome-labelled antibodies are made by conjugating a fluorochrome to the antibody, a process also known as tagging. A process called fluorescent antigen technique can also be used. In this process, an antigen is conjugated to the antibody with a fluorescent probe. WebNov 5, 2024 · However, the most widely used fluorescent probes for myelin visualization, such as Vybrant DiD and FluoroMyelin, have strong background staining, low-staining contrast, and low brightness. These drawbacks may originate from their self-quenching properties and greatly limit their applications in three-dimensional (3D) imaging and …
