Background
NCAM, as a member of the immunoglobulin superfamily of adhesion molecules is characterized by several immunoglobulin (Ig)-like domains. The extracellular part of NCAM consists of five of these Ig domains and two fibronectin type III homology regions. NCAM is encoded by a single copy gene composed of 26 exons. However, at least 20-30 distinct isoforms can be geneRated by alternative splicing and by posttranslational modifiCations, such as sialylation. During sialylation, polysialic acid (PSA) carbohydRates are attached to the extracellular part of NCAM. Through its extracellular region, NCAM mediates homophilic interactions. In addition, NCAM can also undergo heterophilic interactions by binding extracellular matrix components, such as laminin, or other cell adhesion molecules, such as integrins.

Source
NKI-NBl-1 is a Mouse monoclonal IgG1 antibody derived by fusion of SP2/0 Mouse myeloma cells with spleen cells from a BALB/c Mouse immunized with neuroblastoma cell line CHP-212.

Product
Each vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.

Formulation: Each vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.

Specificity
Different antibodies recognize a heterodimeric glycoprotein of 145, 185 kD which has been identified as NCAM (Neural Cell Adhesion Module). Two major epitopes have been defined, NKI-nbl-1 (art. nr. MUB1321S and MUB1321P) reacts with epitope 1 and 123C3 (art. nr. MUB1301S and MUB1301P) reacts with epitope 2.

Applications
NKI-nbl-1 is useful for immunofluorescence, immunoprecipitation and immunohistochemistry on frozen tissues. Optimal antibody dilution should be determined by titration.

Storage
The antibody is shipped at ambient temperature and may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.
