Description

NEUROBIOTIN 488 Tracer is a tri-functional molecule designed for neuronal tracing and cell filling.

Features:

  • Bright green fluorophore, similar in fluorescence to fluorescein, Cy2 or Alexa Fluor® 488
  • Biotin label with a biotinidase-resistant linkage
  • Fixable primary amine
  • Used for visualizing neural architecture and for the identification of gap junction coupling
  • Can be used in many types of preparations including in vivo, whole mounts, slice preparations, or cultured cells
  • Can be delivered by many routes such as intracellular electrodes, microinjection, cut-loading, or scrape-loading

Advantages of NEUROBIOTIN Tracer over biocytin and other neuronal labels:

  • Better solubility
  • More efficiently iontophoresed
  • Remains in cell longer
  • Non-toxic
  • Can be fixed with formalin or glutaraldehyde
