Order Now

  • Synonym
    LAIR1,CD305
  • Source
    Human LAIR-1, Mouse IgG2a Fc Tag(LA1-H5253) is expressed from human 293 cells (HEK293). It contains AA Gln 22 - His 163 (Accession # Q6GTX8-1).
    Predicted N-terminus: Gln 22
  • Molecular Characterization
    LAIR-1 Structure

    This protein carries a mouse IgG2a Fc tag at the C-terminus.

    The protein has a calculated MW of 42.3 kDa. The protein migrates as 55-60 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, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.

Immobilized Human Collagen I protein at 2 μg/mL (100 μL/well) can bind Human LAIR-1, Mouse IgG2a Fc Tag (Cat. No. LA1-H5253) with a linear range of 10-78 ng/mL (QC tested).

  • Background
    Leukocyte-associated immunoglobulin-like receptor-1 (LAIR-1) is constitutively expressed on the majority of human peripheral blood mononuclear leukocytes. LAIR-1 or CD305 is a transmembrane glycoprotein with a single immunoglobulin-like domain and a cytoplasmic tail containing two immune receptor tyrosine-based inhibitory motifs. LAIR-1 recruits SHP-1 and SHP-2 phosphatases upon activation, and cross-linking of the LAIR-1 antigen on natural killer (NK) cells results in strong inhibition of NK cell–mediated cytotoxicity.
    Functions as an inhibitory receptor that plays a constitutive negative regulatory role on cytolytic function of natural killer (NK) cells, B-cells and T-cells. Activation by Tyr phosphorylation results in recruitment and activation of the phosphatases PTPN6 and PTPN11. It also reduces the increase of intracellular calcium evoked by B-cell receptor ligation.Diseases associated with LAIR1 include Chronic Active Epstein-Barr Virus Infection and Palindromic Rheumatism.
