About Keratin, LMW
The cytokeratins can be divided into low versus high molecular weight solely based on their molecular weight. Expression of these cytokeratins is frequently organ or tissue specific. As an example, CK7 is typically expressed in the ductal epithelium of the genitourinary (GU) tract and CK20 most commonly in the gastrointestinal (GI) tract. Anatomic pathologists employ such distinctions to detect the cell of origin of various tumors.
