Biocytin  (Synonyms: (+)-Biocytin)

Cat. No.: HY-101884 Purity: 99.52%
COA Handling Instructions

Biocytin is a conjugate of D-biotin and L-lysine, where the carboxylate of D-biotin is coupled with the ?-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.

Description

Biocytin is a conjugate of D-biotin and L-lysine, where the carboxylate of D-biotin is coupled with the ?-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].

Human Endogenous Metabolite

 

In Vitro

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
