Description

Description: The monoclonal antibody 12E3 specifically recognizes polysialylated neural cell adhesion molecule (PSA-NCAM) in human, mouse and rat. Polysialic acid is a long homopolymer of sialic acid that is negatively charged and is attached to neural cell adhesion molecule (CD56) and serves as a regulator of NCAM function. PSA attachment to NCAM is associated with inhibited adhesion of neural cells. PSA-NCAM expression is highly regulated and corresponds to specific neural developmental windows in which neural precursors are migrating and during the process of axonal sprouting, guidance, and targeting. PSA-NCAM expression is prevalent during development of the brain, but in the adult becomes restricted to regions undergoing self-renewal or exhibiting plasticity such as the olfactory bulb, suprachiasmatic nucleus, hippocampus, hypothalamus, and specific spinal cord nuclei. PSA-NCAM is re-expressed during tumorigenesis and is also expressed on cell lines isolated from neuroblastomas and pheochromocytomas. Applications Reported: This 12E3 antibody has been reported for use in immunohistochemical staining of frozen tissue sections, immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, microscopy, and immunocytochemistry. Applications Tested: This 12E3 antibody has been tested by immunocytochemistry of formaldehyde-fixed PC-12 (rat) cells and can be used at less than or equal to 20 μg/mL.
