Biocytin 是一种D-生物素和L-赖氨酸的共轭物，D-生物素的羧酸盐通过仲酰胺键与L-赖氨酸的 α-胺偶联。它是神经解剖学示踪剂，通常用于绘制大脑的连接性。它在顺逆行和细胞内神经解剖学研究以及生物素酶测定中用作通用标记物。

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 ε-amine of L-lysine via a secondary amide bond.

Biocytin is used as a versatile marker in anterograde, retrograde and intracellular neuroanatomical investigations and in biotinidase assays. Biocytin wide-field bipolar cell is an ON blue cone bipolar cell in the rabbit retina and is homologous to the blue cone bipolar cells that have been previously described in primate, mouse, and ground squirrel retinas[2].
