Biotinylated Human LILRB2 / CD85d / ILT4 Protein, Fc Tag, Avi Tag (Avitag™)

  • Synonym
    LILRB2,ILT4,LIR2,MIR10,CD85d
  • Source
    Biotinylated Human LILRB2, Fc Tag (LI2-H82F5) is expressed from human 293 cells (HEK293). It contains AA Gln 22 - Val 461 (Accession # AAH36827.1).
    Predicted N-terminus: Gln 22
  • Molecular Characterization
    LILRB2(Gln 22 - Val 461) AAH36827.1

    This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag (Avitag™).

    The protein has a calculated MW of 76.2 kDa. The protein migrates as 36 kDa and 100-116 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Biotinylation
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Biotin:Protein Ratio
    The biotin to protein ratio is 0.5-1 as determined by the HABA assay.
  • 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 50 mM Tris, 100 mM Glycine, pH7.5. 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
Biotinylated Human LILRB2, Fc Tag (Cat. No. LI2-H82F5) SDS-PAGE gel

Biotinylated Human LILRB2, 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 90%.

Bioactivity

Immobilized Human ANGPTL7, His Tag (Cat. No. AN7-H52H5) at 5 μg/mL (100 μL/well) can bind Biotinylated Human LILRB2, Fc Tag (Cat. No. LI2-H82F5) with a linear range of 0.156-2.5 μg/mL (QC tested).

  • Background
    Leukocyte immunoglobulin-like receptor subfamily B member 2 (LILRB2) is also known as CD85 antigen-like family member D (CD85d), Immunoglobulin-like transcript 4 (ILT-4), Monocyte / macrophage immunoglobulin-like receptor 10 (MIR-10), which is a member of the the subfamily B class of LIR receptors. LILRB2 is receptor for class I MHC antigens. LILRB2 recognizes a broad spectrum of HLA-A, HLA-B, HLA-C and HLA-G alleles. LILRB2 competes with CD8A for binding to class I MHC antigens. LILRB2 / CD85d inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions.
