      Background InformationChondroitin sulfate proteoglycan 4 (UniProt: Q00657; also known as Chondroitin sulfate proteoglycan NG2, HSN tumor-specific antigen) is encoded by the Cspg4 (also known as Ng2) gene (Gene ID: 81651) in rat. Chondroitin sulfate proteoglycan NG2 is a single-pass type I membrane protein that plays a role in cell proliferation and migration and stimulates endothelial cells motility during microvascular morphogenesis. It is present in neural cells and in extraneural tissues, especially in the developing mesenchyme. Its level of expression is highest on immature, proliferating cells and decreases when these cells begin to differentiate. It is found on the surfaces of an unusual class of glial cells within the developing and mature central nervous system that have the properties of oligodendrocyte precursor cells. It is a major chondroitin sulfate proteoglycan that is produced after spinal cord injury and is expressed by macrophages and oligodendrocyte progenitors. It is also reported to inhibit neurite outgrowth and growth cone collapse during axon regeneration. NG2 chondroitin sulfate proteoglycan is synthesized with a signal peptide (aa 1-29), which is subsequently cleaved off in the mature form.(Ref.: Jones, LL et al. (2002). J. Neurosci. 22(7):2792-2803).

      ApplicationAnti-NG2 Chondroitin Sulfate Proteoglycan, Cat. No. AB5320, is a rabbit polyclonal antibody that detects rat NG2 Chondroitin Sulfate and is tested for use in Immunohistochemistry and Western Blotting.
      Key Applications
      • Immunohistochemistry
      • Western Blotting
      Application NotesImmunohistochemistry:
      A 1:250 dilution of this antibody detected NG2 Chondroitin Sulfate Proteoglycan in Rat brain hippocampus tissue sections. Care should be taken to avoid overfixing tissue sections.

      Optimal working dilutions and protocols must be determined by end user
      Biological Information
      ImmunogenRecombinant rat Chondroitin sulfate proteoglycan 4 containing amino acids 30 to 2225.
      ConcentrationPlease refer to the Certificate of Analysis for the lot-specific concentration.
      SpecificityNG2 Chondroitin Sulfate Proteoglycan. AB5320 identifies both the intact proteoglycan and the core protein by Western blot and ELISA. When oligodendrocyte precursor cells (i.e. O-2A progenitor cells) are stained alive, the stain appears as clusters on the cell surface. This antibody does not stain differentiated oligodendrocytes well.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: Q6UVK1 # Proteoglycan playing a role in cell proliferation and migration which stimulates endothelial cells motility during microvascular morphogenesis. May also inhibit neurite outgrowth and growth cone collapse during axon regeneration. Cell surface receptor for collagen alpha 2(VI) which may confer cells ability to migrate on that substrate. Binds through its extracellular N- terminus growth factors, extracellular matrix proteases modulating their activity. May regulate MPP16-dependent degradation and invasion of type I collagen participating in melanoma cells invasion properties. May modulate the plasminogen system by enhancing plasminogen activation and inhibiting angiostatin. Functions also as a signal transducing protein by binding through its cytoplasmic C-terminus scaffolding and signaling proteins. May promote retraction fiber formation and cell polarization through Rho GTPase activation. May stimulate alpha-4, beta-1 integrin- mediated adhesion and spreading by recruiting and activating a signaling cascade through CDC42, ACK1 and BCAR1. May activate FAK and ERK1/ERK2 signaling cascades.
