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 a classical neuroanatomical tracer commonly used to map brain connectivity. Biocytin is used as a versatile marker in anterograde, retrograde and intracellular neuroanatomical investigations and in biotinidase assays[1][2].
Due to its high affinity for avidin, Biocytin can be visualized by using a host of avidin-conjugated markers at the light and electron microscopic level. Biocytin is used to visualize the morphology of dendritic and axonal arborizations[1].The Biocytin wide-field bipolar cell in rabbit retina is a sparsely populated ON cone bipolar cell with a broad dendritic arbor that does not contact all cones in its dendritic field. Identification of bipolar cells by selective uptake of Biocytin, labeled the cones with peanut agglutinin, and then identification of cone types using antibodies against blue cone opsin and red-green cone opsin. The Biocytin-labeled cells selectively contact cones whose outer segments stained for blue cone opsin and avoided cones that do not. 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[3].

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
