Biotin tracer
WebIn the claudin-1 −/− mouse epidermis (d–f), the diffusion of injected biotin tracer is not prevented by the occludin-positive TJs ( arrows ). Instead, the biotin tracer passes through these TJs to reach the border between stratum granulosum and stratum corneum. Bar: 10 μm. SC, stratum corneum.

Taken together, the above observations in Tric ... WebPolar tracers such as lucifer yellow CH, Cascade Blue hydrazide, the Alexa Fluor hydrazides and biocytin are membrane-impermeant probes that are usually introduced into cells by whole-cell patch clamping, iontophoresis, osmotic lysis of pinocytic vesicles or comparable methods ( Techniques for loading molecules into the cytoplasm—Table 14.1 ).
WebJul 1, 2013 · Biotin Tracer Experiment The integrity of the BTB was assessed using a biotin tracer as previously described [ 21 ]. Briefly, male mice were anesthetized, and approximately 50 μl of EZ-Link Sulfo-NHS-LC-Biotin (10 mg/ml; 21335; Pierce Chemical Co.), freshly diluted in PBS containing 1 mM CaCl 2 , were injected into one testis. 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.
