Human LGR4 / GPR48 protein, His Tag

  • Synonym
    LGR4, GPR48, G-protein coupled receptor 48, Leucine-rich repeat-containing G-protein coupled receptor 4
  • Source
    Human LGR4, His Tag (LG4-H52H3) is expressed from human 293 cells (HEK293). It contains AA Ala 25 -Thr 544 (Accession # Q9BXB1-1).
  • Molecular Characterization
    Online(Ala 25 -Thr 544) Q9BXB1-1

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

    The protein has a calculated MW of 58.8 kDa. The protein migrates as 66-90 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

    >85% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

  • 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.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
Human LGR4, His Tag (Cat. No. LG4-H52H3) SDS-PAGE gel

Human LGR4, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 85%.

Bioactivity-ELISA

Immobilized Human R‑Spondin 3 at 2 μg/mL (100 μL/well) can bind Human LGR4, His Tag (Cat. No. LG4-H52H3) with a linear range of 10-78 ng/mL (QC tested).

Bioactivity-SPR
Human_FcRn_Heterodimer_Protein_SPR

Human R-Spondin 3 immobilized on CM5 Chip can bind Human LGR4, His Tag (Cat. No. LG4-H52H3) with an affinity constant of 0.394 μM as determined in a SPR assay (Biacore T200) (Routinely tested).

  • Background
    The fourth member of the leucine-rich repeat-containing GPCR family (LGR4, frequently referred to as GPR48) together with its family members LGR5 and -6, bind to R-spondins (RSPOs)-1–4 and result in Wnt signaling potentiation. In addition, LGR4 (as well as LGR5 and -6) is implicated in multiple cancers and promotes invasion and metastasis in colorectal, prostate, and cervical cancer cell lines.
