Keratins refers to a set of immunostains that mark filaments that are characteristic of epithelial cells and cancer derived from epithelial cells (carcinomas).
Keratin when used in singular may refer to pankeratin.
Classification
Divided by molecular weight:[1]
- Low molecular weight keratins (LMWK): 7, 8/18, 19, 20.
- High molecular weight keratins (HWMK): 4, 10, 13, 14, 17.
Uses
- CK8 (CAM5.2)[2] - used to look for mets from breast cancer in axillary lymph nodes.
- HWMK (e.g. K903[3]) - squamous cell carcinoma.
