Quantitative sandwich ELISA for measuring Bovine Cytokeratin fragment antigen 21-1 (CYFRA21-1) in samples from cell culture supernatants, serum, whole blood, plasma and other biological fluids.

• Additional information:Cytokeratins are structural proteins forming the subunits of epithelial intermediary filaments. Fragments of cytokeratin-19 (CYFRA 21-1) are frequently released into the blood of cancer patients. Due to the high specificity relative to benign lung diseases,it is suitable for use as a differentiation marker in tumor pathology especially in lung cancer.
