Cancer CYFRA 21-1 Immunoradiometric Assay as a Marker of Lung Serum Fragment of Cytokeratin Subunit 19 Measured by Updated

Cytokeratin 19 is a subunit of cytokeratin intermediate filament ex pressed in simple epithelia and their malignant counterparts. Therefore, it is expressed by respiratory epithelium cells and has been detected in lung cancer specimens. An immunoradiometric assay was used to detect a fragment of the cytokeratin 19, referred to as CYFRA 21-1, in the serum of… CONTINUE READING
