CYFRA21-1 Recombinant Protein

Target/reference protein material for calibration or control concepts, antibody characterization and analytical evaluation in CYFRA21-1-related assay development. CK19-fragment tumor-marker target used mainly in NSCLC monitoring and contextual assessment.

Target/reference protein material for calibration or control concepts, antibody characterization and analytical evaluation in CYFRA21-1-related assay development. CK19-fragment tumor-marker target used mainly in NSCLC monitoring and contextual assessment. CYFRA21-1 is a circulating cytokeratin-19 fragment associated with epithelial turnover. Evidence in NSCLC is strongest for contextual/longitudinal monitoring, while benign pulmonary/inflammatory and renal factors can confound interpretation.
