      DescriptionAnti-NG2, Alexa Fluor®488 Conjugate Antibody
      Alternate Names
      • Chondroitin sulfate proteoglycan 4
      • Chondroitin sulfate proteoglycan NG2
      • Melanoma chondroitin sulfate proteoglycan
      • Melanoma-associated chondroitin sulfate proteoglycan
      Background InformationNG2 is a high molecular weight, integral membrane chondroitin sulfate proteoglycan. 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 (i.e., O-2A progenitor cells). NG2 is also found on the surfaces of chondroblasts, proliferating capillary endothelial cells, some human melanoma cell lines, and on leukemic blasts in childhood acute lymphoblastic leukemia. The NG2 proteoglycan is likely to play a role in regulation of cell motility, axon outgrowth and the cellular responses to platelet-derived growth factor.
      Product Information
      • Rat oligodendrocyte precursor cells
      PresentationPurified rabbit polyclonal conjugated to Alexa Fluor® 488 in PBS with 0.1% sodium azide and 15 mg/mL BSA.
      ApplicationAnti-NG2, Alexa Fluor®488 Conjugate Antibody detects level of NG2 & has been published & validated for use in ICC & IHC.
      Key Applications
      • Immunocytochemistry
      • Immunohistochemistry
      Application NotesImmunohistochemistry Analysis: A 1:100 dilution from a representative lot detected NG2 in adult rat brain tissue.
      Biological Information
      ImmunogenImmunoaffinity purified NG2 Chondroitin Sulfate Proteoglycan from rat
      SpecificityThis antibody identifies the intact proteoglycan and core protein by WB 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.

      Entrez Gene Number
      Entrez Gene SummaryA human melanoma-associated chondroitin sulfate proteoglycan plays a role in stabilizing cell-substratum interactions during early events of melanoma cell spreading on endothelial basement membranes. CSPG4 represents an integral membrane chondroitin sulfate proteoglycan expressed by human malignant melanoma cells.

      UniProt Number
      UniProt SummaryFUNCTION: 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.
