mouse monoclonal IgG1; GBP1-5 Antibody (G-12) is an IgG1 κ mouse monoclonal GBP1-5 antibody (also designated pan GBP antibody, pan reactive Guanylate Binding Protein antibody, broad reactivity GBP antibody, GBP family antibody, GBP1 antibody, Guanylate Binding Protein 1 antibody, Guanylate Binding Protein 1 Interferon-Inducible antibody, Interferon-Induced Guanylate-Binding Protein antibody, Guanine Nucleotide-Binding Protein 1 antibody, Guanylate-Binding Protein 1 antibody, GTP-Binding Protein 1 antibody, HuGBP-1 antibody, GBP-1 antibody, or Guanylate Binding Protein 1 Interferon-Inducible antibody) that detects the GBP1-5 protein of mouse, rat and human origin by WB, IP, IF, IHC(P) and ELISA. GBP1-5 Antibody (G-12) is available as both the non-conjugated anti-GBP1-5 antibody form, as well as multiple conjugated forms of anti-GBP1-5 antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. Guanylate-binding proteins (GBP) GTP-binding proteins with a high-turnover GTPase activity and an antiviral effect. GBP proteins belong to a group of large GTP-binding proteins with a high concentration-dependent GTPase activity and a common ability to undergo oligomerization. GBP proteins are bone marrow-derived GTPases encoded by interferon-activated genes and are inducible following IFN treatment.
