Immunohistochemistry (IHC) counterstains and special stains

Tailored reagents for your IHC experiments.

IHC stains provide contrast after immunodetection to improve visualization of the primary label or to stain specific structures. Both chromogenic and fluorescent counterstains are available.

Special stains

Special stains are valuable in non-routine immunohistochemical staining for the identification of specific cells, tissues and organisms. Special stains are also useful for the evaluation of disease states and can be used in cell biology and histology.
