Mouse Anti-Human CD56 (Clone ERIC-1) recognizes an epitope on Human CD56. This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

Anti-Human CD56 can be used in studies of the neural cell adhesion molecule. This antibody may also be used to study isoforms of NCAM expressed on different tumor types. Anti-CD56 (clone ERIC-1) works well in western blot for analysis of isoforms expressed. Anti-CD56 did not react with any of the leukemias or lymphomas tested.¹

The CD56 (NCAM) antigen is expressed on most neuroectodermal derived cell lines, tissues, and tumors. NCAM is also known to be expressed on some mesodermally derived tissues such as muscle¹ and on natural killer (NK) lymphocytes. The binding of ERIC-1 to both normal and neoplastic tissue is lost when tissues are conventionally fixed in formalin and embedded in paraffin. The epitope was preserved when exposed to dehydrating fixatives such as cold acetone (-20°C) for 5 min. CD56 is present on 10-25% of peripheral blood lymphocytes.
