Biocytin is a conjugated adduct of L-lysine and D-biotin. It is hydrolyzed by biotinidase, which acts on peptide-incorporated biotin or free biotin. Biocytin acts as a coenzyme. Biocytin is used as a substrate to study the specificity and kinetics of biotinidase(s), to measure biotinidase deficiency and as a model compound to study various uptake mechanisms of cells and tissues. Biocytin has been used to label neurons, medium spiny neurons and optic nerves.
