Cytonel Plus kit

The Cytonel Plus kit offers reagents for rapid pan-cytokeratin immunostaining, which is intended to assist the pathologist, who makes a rapid intraoperative histopathologic diagnosis using frozen sections. The kit enables immunostaining to be done in ~6 min.

Cytonel Plus kit content:

  • Endogenous peroxidase blocker
  • Peroxidased-conjugated Fab2 fragment of a pan-cytokeratin antibody, which is optimised for the ultrarapid staining protocol. The antibody is a cocktail of four mouse monoclonal antibodies. The antibody reacts with an epitope which is present in cytokeratins 4, 5, 6, 8, 10, 13, 18, and 19.
  • Diamino benzidine (DAB) chromogen and dilution buffer
  • Washing buffer (PBS-tween) concentrate

Kits for sized 20 and 100 slides are available.
