Scientific Data Images for Human/Mouse NCAM‑1/CD56 Antibody

Detection of Human and Mouse NCAM-1/CD56 antibody by Western Blot.

Detection of Human and Mouse NCAM‑1/CD56 by Western Blot.

Western blot shows lysates of human brain (cerebellum and motor cortex) tissue and mouse brain (cerebellum) tissue. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse NCAM-1/CD56 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2408) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). Specific bands were detected for NCAM-1/CD56 at approximately 100-150 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
NCAM-1/CD56 antibody in SH-SY5Y Human Neuroblastoma Cells by Immunocytochemistry (ICC).

NCAM-1/CD56 in SH-SY5Y Human Neuroblastoma Cells.

SH-SY5Y human neuroblastoma cells were cultured overnight in the presence of 1 μM Retinoic Acid (0695/50) prior to immersion fixation. Neural Cell Adhesion Molecule 1 (NCAM-1)/CD56 was detected using a Goat Anti-Human/Mouse NCAM-1/CD56 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2408). The cells were stained with the NorthernLights 557-conjugated Donkey Anti-Goat IgG Affinity-purified Secondary Antibody (red; Catalog # NL001). Actin filaments were stained with FITC-conjugated Phalloidin (green) and cell nuclei were counter-stained with DAPI (blue). NCAM-1/CD56 immuno-reactivity was localized to the plasma membrane.

NCAM-1/CD56 antibody in BG01V Human Embryonic Stem Cells by Immunocytochemistry (ICC).

NCAM‑1/CD56 in BG01V Human Embryonic Stem Cells.

NCAM-1/CD56 was detected in immersion fixed BG01V human embryonic stem cells differentiated into neural progenitor cells using Goat Anti-Human/Mouse NCAM-1/CD56 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2408) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: NCAM-1/CD56

Neural cell adhesion molecule 1 (NCAM-1) is a multifunctional member of the Ig superfamily. It belongs to a family of membrane-bound glycoproteins that are involved in Ca++ independent cell matrix and homophilic or heterophilic cell-cell interactions. NCAM-1 specifically binds to heparan sulfate proteoglycans (1), the extracellular matrix protein agrin (2), and several chondroitin sulfate proteoglycans that include neurocan and phosphocan (3). There are three main forms of human NCAM-1 that arise by alternate splicing. These are designated NCAM-120/NCAM-1 (761 amino acids [aa]), NCAM-140 (848 aa), and NCAM-180 (1120 aa). NCAM-120 is GPI-linked, while NCAM-140 and NCAM-180 are type I transmembrane glycoproteins (4‑6). Additional alternate splicing adds considerable diversity to all three forms, and extracellular proteolytic processing is possible for NCAM-180 (7‑8). NCAM-1 is synthesized as a 761 aa preproprecursor that contains a 19 aa signal sequence, a 722 aa GPI-linked mature region, and a 20 aa C-terminal prosegment (4). The molecule contains five C-2 type Ig-like domains and two fibronectin type-III domains. Human to mouse, NCAM-1 is 93% aa identical. NCAM-1 appears to be highly sialylated. The polysialyation of NCAM-1 reduces its adhesive property and increases its neurite outgrowth promoting features (9). NCAM-1 in the adult brain shows a decline of sialylation relative to earlier developmental periods. In regions that retain a high degree of neuronal plasticity, however, the adult brain continues to express polysialylation-NCAM-1, suggesting sialylation of NCAM-1 is involved in regenerative processes and synaptic plasticity (10‑13).
