Product details:
Human LAIR2 ELISA Kit (ab277432) is an
in-vitro
enzyme-linked immunosorbent assay for the quantitative measurement of Human LAIR2 in serum (human LAIR2 concentration is low in normal serum/plasma, and may not be detectable in this assay), plasma and cell culture supernatants.
This assay employs an antibody specific for Human LAIR2 coated on a 96-well plate. Standards and samples are pipetted into the wells and Human LAIR2 present in a sample is bound to the wells by the immobilized antibody. The wells are washed, and biotinylated anti-Human LAIR2 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Human LAIR2 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

The Leukocyte-Associated Immunoglobulin-like Receptor 2 (LAIR2) also known as CD306 is a soluble protein with a mass of approximately 15.2 kDa. It can be found in serum where immune system regulation occurs. Structurally LAIR2 shares similarities with LAIR1 a membrane-bound protein although LAIR2 lacks a transmembrane domain. It acts by sequestering ligands that would interact with LAIR1 thereby modulating the immune system response.
Biological function summary
LAIR2 regulates immune cell function by inhibiting collagen-induced signaling that typically activates immune responses. LAIR2 functions independently without forming a complex with other cell surface receptors or signaling molecules. By binding to collagens this protein limits unnecessary immune activation acting as a checkpoint in immune regulation and maintaining tolerance.
Pathways
Multiple immune regulatory pathways involve LAIR2 including the collagen signaling pathway that modulates immune cell activity. LAIR2 is related to LAIR1 since they both respond to collagen interactions in the immune system. Disruption in these pathways may affect immune homeostasis linking LAIR2 directly to collagen-mediated modulation.
Disturbances in LAIR2 expression have links with autoimmune disorders and chronic inflammatory conditions. The protein is of particular interest in studies on systemic lupus erythematosus where altered LAIR2 levels can influence disease progression. Additionally LAIR2 connections with LAIR1 suggest potential implications in fibrotic diseases identifying it as a therapeutic target for modulating immune responses.
