介绍
Biocytin hydrazide can be used as microinjectable anterograde and transneuronal tracers that is fixable with aldehyde-based fixatives. Additionally, the primary aliphatic amine of this molecule can be reversibly coupled to aldehydes and ketones to form a Schiff base – which can be reduced to a stable amine derivative by sodium borohydride (NaBH4) or sodium cyanoborohydride (NaCNBH3) to form new biotinylated probes. Carboxylic acids of proteins and other water-soluble biopolymers can be coupled to this molecule in aqueous solution using water-s......

介绍
The water-soluble neuronal tracer 5-(and-6)-tetramethylrhodamine biocytin (biocytin TMR) can be detected in fixed tissues by using avidin or streptavidin probes. However, tetramethylrhodamine biocytin can also be observed directly in fixed or unfixed samples because the attached tetramethylrhodamine dye produces bright, orange-fluorescence (absorption/emission maxima ~555/580 nm).

Biocytin can be used as microinjectable anterograde and transneuronal tracers that is fixable with aldehyde-based fixatives. Additionally the primary amine on the lysine can be reversibly coupled to aldehydes and ketones to form a Schiff base – which can be reduced to a generate stable amine derivative by sodium borohydride (NaBH4) or sodium cyanoborohydride (NaCNBH3). Carboxylic acids of proteins and other water-soluble biopolymers can be coupled to this molecule in aqueous solution using water-soluble carbodiimides such as EDAC.
