Investigators have identified rapid degradation of injected tracers such as biocytin due to the presence of biotinidase activity in brain tissue*. This loss of stability of the tracer significantly reduces the viable postinjection period and may compromise complete detection of a neural network. NEUROBIOTIN-Plus was designed to be impervious to cleavage and breakdown by biotinidase. This newly synthesized biotin-containing compound contains fixable amine groups, is highly soluble and has a low molecular weight. These characteristics make it an ideal candidate for experiments requiring long postinjection survival times and optimal uptake along the entire neural tract.
NEUROBIOTIN-Plus shares the same key advantages of NEUROBIOTIN Tracer over biocytin and other neuronal labels:
NEUROBIOTIN-Plus can be detected using avidin or streptavidin systems with either chromogenic or fluorescence visualization methods.
