Human LILRA4 / CD85g / ILT7 Protein, His Tag

  • Synonym
    LILRA4,CD85g,ILT7,ILT-7
  • Source
    Human LILRA4 Protein, His Tag(LI4-H52H5) is expressed from human 293 cells (HEK293). It contains AA Glu 24 - Asn 446 (Accession # P59901-1).
    Predicted N-terminus: Glu 24
  • Molecular Characterization
    LILRA4 Structure

    This protein carries a polyhistidine tag at the C-terminus

    The protein has a calculated MW of 48.5 kDa. The protein migrates as 60-66 kDa 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.

    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.

    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
LILRA4 SDS-PAGE

Human LILRA4 Protein, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90%.

Bioactivity-ELISA
 LILRA4 ELISA

Immobilized Human LILRA4 Protein, His Tag (Cat. No. LI4-H52H5) at 2 μg/mL (100 μL/well) can bind Monoclonal Anti-LILRA4 Antibody, Human IgG1 with a linear range of 0.001-0.063 μg/mL (QC tested).

  • Background
    Leukocyte immunoglobulin-like receptor subfamily A member 4 (LILRA4/ILT7/CD85g) is a marker of plasmacytoid dendritic cells (pDCs), which are reported to be a major source of the abnormally high levels of IFNα associated with autoimmune diseases. Targeting LILRA4 with therapeutic antibodies to promote killing of these IFNα-producing pDCs is being investigated as a novel approach to alleviating the symptoms of autoimmune diseases. LILRA4 is an immunoglobulin-like protein preferentially expressed on the surface of human plasmacytoid dendritic cells (pDCs). It interacts with bone marrow stromal cell antigen 2 to control the Toll-like receptor (TLR) driven response by pDCs to viral infection. It may also be involved in modulating pDC-tumour interactions. pDCs are a source of the excess IFNα which drives autoimmune disease symptoms.
