All IHC stains will include a positive control tissue

• Wide-spectrum cytokeratin cocktail, used in identifying epithelium
• This is currently the best cytokeratin available on the market, for covering the most cytokeratins

Submit a formalin-fixed, paraffin-embedded tissue

Formalin-fixed, paraffin-embedded (FFPE) tissue block

FFPE tissue section mounted on a charged, unstained slide

Ambient (preferred)

• Unlabeled/mislabeled block
• Insufficient tissue
• Slides broken beyond repair

Immunohistochemical staining and microscopic examination

If requested, an interpretive report will be provided

Specifications

• Cytokeratin cocktail that recognizes a spectrum of cytokeratin intermediate filaments
• Identifies most epithelial types (except epidermis of skin, where it usually only stains basal layer)

Staining pattern

• Cytoplasmic staining
