Cat.No. 6241 - Biotinyl Tyramide | C18H25N3O3S | CAS No. 41994-02-9
Description: Reagent widely used for signal amplification in IHC and ISH
Chemical Name: (3aS,4S,6aR)-Hexahydro-N-[2-(4-hydroxyphenyl)ethyl]-2-oxo-1H-thieno[3,4-d]imidazole-4-pentanamide
Purity: ≥98% (HPLC)

Biological Activity

Reagent widely used for signal amplification in IHC and in situ hybridization (ISH). HRP catalyzes localized deposition of multiple biotinyl tyramide molecules (catalyzed reporter deposition, CARD), which can be detected using a labeled streptavidin conjugate. The localization of deposition around HRP leads to good resolution. Suitable for either fluorescence or chromogenic detection.
