In vivo proximity labeling
WebFeb 16, 2024 · Here, we describe the development, and application, of a new method for proximity-dependent biotin labelling in whole zebrafish. Using a conditionally stabilised … WebProximity labeling relies on a labeling enzyme that can biotinylate nearby biomolecules promiscuously. Biotin labeling can be achieved through several different methods, depending on the species of labeling enzyme. BioID, also known as BirA*, is a mutant E. coli biotin ligase that catalyzes the activation of biotin by ATP.
