  • 产品描述：

    IGFBP2 is a pleiotropic polypeptide that functions as autocrine and/or paracrine growth factors. IGFBP2 is most abundant in the cerebrospinal fluid (CSF) and highly expressed in the developing brain. It plays an essential role in several key oncogenic processes, such as tumor cellular proliferation, migration, invasion, angiogenesis, epithelial‑to‑mesenchymal transition, and immunoregulation. Aberrant overexpression of IGFBP2 is linked to an aggressive phenotype of multiple human cancers, including glioma, ovarian, prostate, and pancreatic carcinomas. High circulating IGFBP2 levels may serve as a useful diagnostic or prognostic tumor biomarker in many types of cancer and are closely associated with relapse and a poorer outlook for patients with cancer.

    The recombinant IGFBP2 antibody was prepared by obtaining the antibody genes, cloning the genes into a plasma vector to construct vector clone, transfecting the vector clone into a mammalian cell line for transient expression, and purifying the antibody by Affinity-chromatography. This recombinant IGFBP2 antibody has been verified to detect the IGFBP2 protein from Human in the ELISA, WB, IHC.

  • 功能：
    Inhibits IGF-mediated growth and developmental rates. IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors.
