Product Description

Cyanine 555  tyramide conjugate is used for TSA in multicolor immunocytochemistry (ICC), immunohistochemistry (IHC), or in situ hybridization (ISH). The HRP-catalyzed method enables high-density labeling of a target protein or nucleic acid with Cyanine 555. Multiple tyramide conjugates are deposited onto tyrosines adjacent to the target for enhanced fluorescent signal. Cyanine 555 is structurally identical to Cy®3 from GE Healthcare.

  • Orange-red fluorescent TSA reagent identical to Cy®3
  • High-density labeling of a target protein or nucleic acid for enhanced immunofluorescence sensitivity
  • Especially suited for the detection of low abundance targets
  • Detection sensitivity of over 100-fold compared to conventional procedures
  • Enables multiplex multicolor detection

We also offer CF®555 tyramide , a superior alternate to Cy®3 with better photostability and brightness.
