Product Specific Information

The antibody recognizes a transmembrane glycoprotein of 140 and 180 kD which has been identified as NCAM (Neural Cell Adhesion Module). At the international Workshop on SCLC antibodies 123C3 has been categorized as cluster 1 antibody. All cells in small cell carcinomas and carcinoids of the lung are strongly positive for 123C3. A minority of cases of other major types of lung carcinoma are sometimes positive as well: however this positivity is generally weak and focal. Adenoid cystic carcinomas of bronchial glands are strongly positive. Neuroblastoma`s and Wilms tumors are usually also staining strongly positive. In non-small lung cell carcinomas, 123C3 staining has been associated with more advanced stage and a decreased survival after surgery. Furthermore, this antibody can be used to support diagnosis of lymphoma or to detect residual disease for cases of CD56 positive T/NK -cell lymphoma in which the neoplastic lymphoid cells are small and show minimal atypia, especially in small biopsies.

Target Information

CD56 (NCAM, neural cell adhesion molecule) is a transmembrane glycoprotein of the immunoglobulin family that serves as an adhesive molecule and is ubiquitously expressed in the nervous system in isoforms ranging from 120-180 kDa. CD56 is found on T cells and NK cells, and is involved in cell migration, axonal growth, pathfinding and synaptic plasticity. Polysialic modification results in reduction of CD56-mediated cell adhesion. Through its extracellular region, CD56 mediates homophilic and heterophilic interactions by binding extracellular matrix components such as laminin and integrins. CD56 is expressed on most neuroectodermal derived cell lines, tissues and neoplasms such as retinoblastoma, medulloblastoma, astrocytomas and neuroblastoma. Further, CD56 is a widely used neuroendocrine marker with a high sensitivity for neuroendocrine tumors and ovarian granulosa cell tumors. Diseases associated with CD56 dysfunction include rabies and blastic plasmacytoid dendritic cell neoplasms.
