Human Gremlin / GREM1 Protein, Fc Tag

  • Synonym
    GREM1,CKTSF1B1,DAND2,DRM,PIG2
  • Source
    Human Gremlin / GREM1, Fc Tag (GR1-H5254) is expressed from human 293 cells (HEK293). It contains AA Lys 25 - Asp 184 (Accession # NP_037504).
    Predicted N-terminus: Lys 25
  • Molecular Characterization
    Gremlin(Lys 25 - Asp 184) NP_037504

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 44.2 kDa. The protein migrates as 48-60 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5 with 1 mM EDTA. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    No activity loss is observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
Human Gremlin / GREM1, Fc Tag (Cat. No. GR1-H5254) SDS-PAGE gel

Human Gremlin / GREM1, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

Bioactivity
Human Gremlin / GREM1, Fc TagHuman Gremlin / GREM1, Fc Tag (Cat. No. GR1-H5254) ELISA bioactivity

Immobilized Human BMP-2, Tag Free (Cat. No. BM2-H4117) at 2μg/mL (100 μL/well) can bind Human Gremlin, Fc Tag (Cat. No. GR1-H5254) with a linear range of 0.8-80 ng/mL (QC tested).

  • Background
    Gremlin is also known as Cysteine knot superfamily 1, BMP antagonist 1 (CKTSF1B1), DAN domain family member 2 (DAND2), Down-regulated in Mos-transformed cells protein (DRM), Increased in high glucose protein 2 (IHG-2), Cell proliferation-inducing gene 2 protein (PIG2) or Gremlin-1 (GREM1), which is highly expressed in small intestine, fetal brain and colon. Gremlin / GREM-1 interacts with SLIT1 and SLIT2 in a glycosylation-dependent manner. Gremlin may play an important role during carcinogenesis and metanephric kidney organogenesis, as a BMP antagonist required for early limb outgrowth and patterning in maintaining the FGF4-SHH feedback loop. Gremlin down-regulates the BMP4 signaling in a dose-dependent manner and acts as inhibitor of monocyte chemotaxis.
