Function
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. May also play its inhibitory role independently of SH2-containing phosphatases. Modulates cytokine production in CD4+ T-cells, down-regulating IL2 and IFNG production while inducing secretion of transforming growth factor beta. Down-regulates also IgG and IgE production in B-cells as well as IL8, IL10 and TNF secretion. Inhibits proliferation and induces apoptosis in myeloid leukemia cell lines as well as prevents nuclear translocation of NF-kappa-B p65 subunit/RELA and phosphorylation of I-kappa-B alpha/CHUK in these cells. Inhibits the differentiation of peripheral blood precursors towards dendritic cells.

Notes
Human LAIR1 Antibody Pair - BSA and Azide free (ab305092) is a matched pair of unconjugated recombinant rabbit monoclonal capture and detection antibodies used to quantify human LAIR1 in sandwich ELISAs and many other pair-based applications.
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
The pair can be used in variety of assays and platforms including but not limited to:
- Sandwich ELISA
- FRET/TR-FRET/HTRF
- Meso Scale Discovery® (MSD®)
- Bead-based assays
- AlphaLISA®/AlphaScreen®
- DELFIA® immunoassays
- Simoa® and Single Molecule Counting (SMC™) immunoassays
- Multiplex
Our antibody pairs are supplied in a carrier-free format that is conjugation-ready:
- Buffer free of BSA, sodium azide, and glycerol for higher conjugation efficiency.
- Concentration of ~1 mg/ml as measured by the protein A280 method.
We can label antibodies for you: get in touch today to discuss how we can help accelerate your assay development with custom conjugation services.
Pairs are screened in biological samples, including plasma and serum, to ensure specificity in complex samples.
Please note:
The recommended antibody orientation is based on internal optimization in sandwich ELISA. Antibody orientation is assay dependent and needs to be optimized for each assay type.
The range provided for this antibody pair is based on initial sandwich ELISA validation data using recombinant protein. Performance and range of the antibody pair will depend on the specific characteristics of your assay, including standard protein selection.
We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibodies in other assays.
Antibody properties:
Capture antibody: recombinant rabbit monoclonal (unconjugated) – 100 µg
Detector antibody: recombinant rabbit monoclonal (unconjugated) - 100 µg

- Activity summary
LAIR1 also known as Leukocyte-Associated Immunoglobulin-like Receptor 1 is a transmembrane protein with a molecular weight of approximately 32 kDa. It expresses mainly on immune cells including T cells B cells and myeloid cells. This receptor by binding to collagen plays a significant role in controlling immune cell signaling. It acts as an inhibitory receptor which helps in maintaining immune system balance and prevents excessive immune responses.
- Biological function summary
LAIR1 functions by modulating immune responses and maintaining homeostasis in the immune system. It is a part of a complex pathway involved in inhibitory signaling. When LAIR1 binds to its ligand such as collagen it transduces a signal that reduces activation of immune cells. This inhibition ensures that immune cells do not become overactive which could otherwise lead to tissue damage.
- Pathways
LAIR1 participates in immune checkpoint regulation and collagen interaction pathways. It interacts with proteins such as ITIM-containing molecules which transmit inhibitory signals essential for regulating immune cell activation. It also indirectly connects to the TGF-beta signaling pathway which is vital for controlling cell differentiation and immune regulation.
- Associated diseases and disorders
LAIR1 is of interest due to its connection to autoimmune diseases and certain cancers. In autoimmune diseases such as rheumatoid arthritis dysregulated LAIR1 signaling may contribute to inflammation. The protein is also linked to cancer where its inhibitory signaling might affect tumor immune evasion. The connection between LAIR1 and these conditions involves proteins like autoimmune-related genes and tumor-associated surface molecules.
