Biotin tracer

WebA tracer composed of biotin coupled to a dextran carrier to prevent its passage through gap junctions has recently been devised ( 18 ). Biotinylated dextran is visualized by staining with an avidin-linked probe. As is the case for enzyme tracers, the embryo must first be fixed. In biochemistry, biotinylation is the process of covalently attaching biotin to a protein, nucleic acid or other molecule. Biotinylation is rapid, specific and is unlikely to disturb the natural function of the molecule due to the small size of biotin (MW = 244.31 g/mol). Biotin binds to streptavidin and avidin with an extremely high affinity, fast on-rate, and high specificity, and these interactions are exploited in many areas of biotechnology to isolate biotinylated molecules of interest. Biotin-bin…
