A20050B_ULEAF_CD273_Antibody_090821
Biotinylated recombinant human PD-L2-Fc chimera (Cat. No. 785904) (black circles) binds to immobilized recombinant human PD-1 (CD279)-Fc chimera (Cat. No. 785106). Ultra-LEAF™ purified anti-human CD273 (B7-DC, PD-L2) (clone A20050B) (purple squares) inhibits the binding in a dose-dependent manner, whereas the GoInVivo™ purified rat IgG2b, κ isotype ctrl antibody (Cat. No. 400666) (gray triangles) does not have the effect. This antibody blocks the binding of 0.2 µg/mL biotinylated recombinant human PD-L2-Fc chimera to 1 µg/mL immobilized recombinant human PD-1 (CD279)-Fc chimera. ND50 range: 0.2 - 1 µg/mL.

Description

PD-L2 is a type I transmembrane protein of 273 amino acids, and it is a member of the B7 family. Human PD-L2 has 70% amino acid identity to its mouse orthologue. PD-L2 is the second ligand for PD-1, and its binding to PD-1 leads to the inhibition of T cell receptor–mediated lymphocyte proliferation and cytokine secretion. PD-L2/PD-1 interaction suppresses immune responses against autoantigens and tumors and plays an important role in the maintenance of peripheral immune tolerance. Antibody blocking of PD-L2 on dendritic cells results in enhanced T cell proliferation and cytokine production. Interaction of PD-1 by PD-L1-Ig or PD-L2-Ig fusion protein has an inhibitory effect on proliferation and cytokine production during anti-CD3-mediated stimulation. PD-L2 is expressed in biopsies from human asthmatics and lungs of aeroallergen-treated mice and its expression correlates with the asthma severity. In vivo blockade of PD-L2 reduces the severity of allergen-driven airway hyperresponsiveness (AHR).  Blockage of PD-L2 induces the IL-12 production by DC; IL-12 may limit the severity of allergen-induced AHR antagonizing IL-13. In addition, blockade of PD-1 does not have effect on AHR; therefore, PD-L2 controls asthma severity in a PD-1 independent manner. PD-L2 binds to a second receptor, RGMb (repulsive guidance molecule b) which is expressed in lung interstitial macrophages and alveolar epithelial cells and is a co-receptor for bone morphogenetic proteins BMP2/4. Blockade of the RGMb/PD-L2 interaction significantly impaired the development of respiratory tolerance since the initial T cell expansion is inhibited.

Related FAQs

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each Ultra-LEAF™ antibody by functional assay?

No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
