Cytokeratin 19 Fragment Antigen 21-1 (CYFRA21-1) Antibody (Capture Ab)
Cytokeratin 19 Fragment Antigen 21-1 (CYFRA21-1), also known as Keratin, type I cytoskeletal 19, cytokeratin-19 (CK-19) or keratin-19 (K19) is a 40 kDa protein that in humans is encoded by the KRT19 gene. Serum CYFRA 21-1 (cytokeratin-19 fragments) may be a reliable marker of recurrence or therapeutic efficacy, and has been used for monitoring the recurrence of breast cancer and in evaluating therapeutic effects. Serum CYFRA 21-1 has also been used as a biomarker for diagnosis of nonsmall cell lung cancer (NSCLC), and has ben reported to be elevated in nasopharyngeal carcinoma (NPC). It can function as a biomarker for detection and monitoring of NPC.
