products description :
Recombinant full length human Cytokeratin 19 protein with molecular weight 40 kDa. Cytokeratin 19 (CK19) belongs to a family of keratins, which are normally expressed in the lining of the gastroenteropancreatic and hepatobiliary tracts. It has been shown to be an independent prognostic factor for pancreatic neuroendocrine tumors, especially the insulin-negative tumors. CK19 positive tumors are associated with poor outcome irrespective of the established pathologic parameters such as size, mitoses, lymphovascular invasion, and necrosis. The low-molecular-weight cytokeratin (CK) protein CK19 has been shown to have diagnostic use and prognostic significance in some types of human malignancy. Cytokeratin-19 alone and its combinations with other markers were more sensitive in accurate diagnosis of papillary carcinoma than the other combinations.
