Description: This CMSSB monoclonal antibody reacts with human CD56, also known as Neural Cell Adhesion Molecule (NCAM). CD56 is a highly glycosylated transmembrane molecule expressed by neurons and plays a role in the homotypic adhesion of neural cells. In the hematopoietic system, CD56 is expressed on NK cells and a subset of T cells referred to as NKT cells. Staining with CMSSB does not block binding of MEM188 or CB56.

Applications Reported: This CMSSB antibody has been reported for use in flow cytometric analysis.

Applications Tested: This CMSSB antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.06 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.

APC-eFluor® 780 emits at 780 nm and is excited with the Red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome.

Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light.

Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.

Excitation: 633-647 nm; Emission: 780 nm; Laser: Red Laser.

Filtration: 0.2 µm post-manufacturing filtered.

靶标信息

CD56, also known as neural cell adhesion molecule (NCAM), is a highly glycosylated transmembrane glycoprotein of the immunoglobulin family. It plays a crucial role in cell adhesion, migration, axonal growth, pathfinding, and synaptic plasticity. CD56 is ubiquitously expressed in the nervous system in isoforms ranging from 120-180 kDa and is involved in homotypic adhesion of neural cells. It mediates interactions by binding extracellular matrix components such as laminin and integrins, with polysialic modification reducing CD56-mediated adhesion. In the hematopoietic system, CD56 is expressed on natural killer (NK) cells and a subset of T cells known as NKT cells. It is also found on most neuroectodermal-derived cell lines, tissues, and neoplasms, including retinoblastoma, medulloblastoma, astrocytomas, and neuroblastoma. CD56 serves as a widely used neuroendocrine marker with high sensitivity for neuroendocrine tumors and ovarian granulosa cell tumors. Diseases associated with CD56 dysfunction include rabies and blastic plasmacytoid dendritic cell neoplasms, highlighting its importance in both neural and immune system functions.
