Biotinylated Human LILRB2 / CD85d / ILT4 Protein, Fc,Avitag™ (MALS verified)

Based on the high binding affinity between biotin-streptavidin systems, our best seller SP-11 Streptavidin Coated Plates are recommended to use together with biotinylated proteins to get lower non-specific binding results in a shorter time.
  • Synonym
    LILRB2,ILT4,LIR2,MIR10,CD85d
  • Source
    Biotinylated Human LILRB2, Fc,Avitag (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
    Online(Gln 22 - Val 461) AAH36827.1

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

    The protein has a calculated MW of 76.2 kDa. The protein migrates as 90-110 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
    Passed as determined by the HABA assay / binding ELISA.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, 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.

The purity of Biotinylated Human LILRB2, Fc,Avitag (Cat. No. LI2-H82F5) is more than 90% and the molecular weight of this protein is around 165-201 kDa verified by SEC-MALS.

  • 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.
