Cytokeratins are regarded as the most fundamental markers of epithelial differentiation.
Based on 2D gel-electrophoresis, keratins are divided into Acid keratins/Type A or Basic keratins /Type B.
Remember- A for Acid keratins and B for Basic keratins
Further, each group is divided into High molecular weight keratins (HMWK) and Low molecular weight keratins (LMWK).
