| Note | THIS PRODUCT IS FOR RESEARCH USE ONLY. NOT FOR USE IN DIAGNOSTIC, THERAPEUTIC OR COSMETIC PROCEDURES. NOT FOR HUMAN OR ANIMAL CONSUMPTION. To keep the original salt concentration, we recommend reconstituting to the original concentration prior to lyophilization (see Concentration) in ddH2O. If a lower concentration is required, dilute in 20 mM Tris, 150 mM NaCl, pH 8.0. If a higher concentration is required, the product can be reconstituted directly in 20 mM Tris, 150 mM NaCl, pH 8.0, though please note that this will change the overall salt concentration. The stock concentration should be between 0.1-1.0 mg/ml. Do not vortex. Concentration: Prior to lyophilization: 500 µg/ml |

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.
