  • Synonym
    IBP2, IGF-BP53
  • Source
    Human IGFBP-2 Protein, His Tag(IG2-H52H4) is expressed from human 293 cells (HEK293). It contains AA Ala 36 - Gln325 (Accession # P18065).
    Predicted N-terminus: Ala 36
  • Molecular Characterization
    IGFBP-2 Structure

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 33.3 kDa. The protein migrates as 33-35 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

 IGFBP-2 ELISA

Immobilized Human IGFBP-2 Protein, His Tag (Cat. No. IG2-H52H4) at 5 μg/mL (100 μL/well) can bind Human IGF-II, Fc Tag (Cat. No. IG2-H4260) with a linear range of 0.1-5 ng/mL (Routinely tested).

  • Background
    The protein encoded by this gene is one of six similar proteins that bind insulin-like growth factors I and II (IGF-I and IGF-II). The encoded protein can be secreted into the bloodstream, where it binds IGF-I and IGF-II with high affinity, or it can remain intracellular, interacting with many different ligands. High expression levels of this protein promote the growth of several types of tumors and may be predictive of the chances of recovery of the patient. Several transcript variants, one encoding a secreted isoform and the others encoding nonsecreted isoforms, have been found for this gene.
