Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate LAIR2 in samples. An antibody specific for LAIR2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyLAIR2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for LAIR2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of LAIR2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:LAIR 2 is a member of the immunoglobulin superfamily. It was identified by its similarity to LAIR1, an inhibitory receptor present on mononuclear leukocytes. This gene maps to a region of 19q13.4, termed the leukocyte receptor cluster, which contains 29 genes in the immunoglobulin superfamily, including LAIR1.
The function of this protein is unknown, although it is thought to be secreted and may help modulate mucosal tolerance. Two transcript variants encoding different isoforms have been found for this gene.By screening a human T-cell cDNA library,Meyaard et al. isolated a LAIR2 cDNA. The predicted LAIR2 protein contains 1 immunoglobulin-like domain, which is 84% homologous to that of LAIR1; it lacks both a transmembrane and a cytoplasmic domain, and therefore the authors suggested that it is secreted.
