N-CAM, Neuronal Cell Adhesion Molecule, CD56Catalog number: NC100
Antibody RNL-1 shows heavy N-CAM expression on cells of the small cell lung carcinoma (SCLC), neuroblastoma, nerves, Leydig-cells, thyroid epithelia and parafollikular cells, pancreas islet cells, adrenal cortex and medulla, and hypophysis. Little differentiated squamous lung tumours may by RNL-1 positive, while adenocarcinoma of the lung are negative. The antibody may be used for differentiating the types of lung tumours. N-CAM is an antigen, that is characteristic of cells of neuroectodermal origin. In the blood it is mainly found on NK-cells (CD56). It is a heavily glycosylated trans-membrane protein. On the 3. International Workshop for Lung tumours and Differentiation antigens (Zürich 1993) N-CAM was assigned to cluster 1 antigens of lung carcinoma (typical for SCLC). Extracellular domain of the N-CAM molecule (200, 100 and 25-27 kDa proteins of NCI-H82 SCLC cell line in western blot).
