Recombinant KRT10 Antibody / Cytokeratin 10

This mAb recognizes a protein of 56.5kDa, identified as cytokeratin 10 (KRT10) . KRT10 is expressed in all suprabasal layers of the epidermis. In the epidermis, expression of KRT10 strictly parallels the extent of differentiation; it is absent in the basal layer, appears in the first suprabasal layers and increases in concentration towards the granular layer. However, KRT10 is rarely detected in early stages of vulvar squamous carcinomas (tumors less than 2 cm, clinical stage I) regardless of the tumor grade. In larger and more advanced tumors (greater than 2 cm, clinical stages II and III), KRT10 is detected very frequently. Expression is related to maturation of malignant keratinocytes, being preferentially detected in more-differentiated parts.
