Biocytin

Description: Biocytin is a classical neuroanatomical tracer commonly used to map brain connectivity. Biocytin is a conjugate of D-biotin and L-lysine, where the carboxylate of D-biotin is coupled with the epsilon-amine of L-lysine via a secondary amide bond. Target: Endogenous Metabolite. Smiles: C(CCCC(NCCCC[C@@H](C(O)=O)N)=O)[C@H]1[C@@]2([C@](CS1)(NC(=O)N2)[H])[H]. References: Roth G, et al.
