Recombinant mouse HVEM-Fc chimera (Cat. No. 771306) (black circles) binds to immobilized recombinant mouse BTLA-Fc chimera (Cat. No. 775806). Ultra-LEAF™ purified anti-mouse CD272 (BTLA) antibody (clone A18238E) (purple squares) inhibits the binding in a dose-dependent manner whereas the GoInViv™ purified rat IgG2a, κ isotype ctrl antibody (Cat. No. 400562) (gray triangles) does not have the effect. Ultra-LEAF™ purified anti-mouse CD272 (BTLA) antibody blocks the binding of 0.03 µg/mL recombinant mouse HVEM-Fc to 1 µg/mL immobilized recombinant mouse BTLA-Fc chimera. ND50 = 0.08 – 0.5 µg/mL.

BTLA (B and T lymphocyte attenuator, CD272) is a type I transmembrane glycoprotein with four extracellular cysteine-rich domains. It is an inhibitory molecule structurally and functionally similar to cytotoxic T lymphocyte antigen-4 (CTLA-4) and programmed death-1 (PD-1). These molecules belong to the immunoglobulin superfamily that binds B7 family members. Different from CTLA-4 and PD-1 binding with the B7 family members, BTLA interacts with herpes virus entry mediator (HVEM) which belongs to TNFR family. BTLA/HVEM interaction was the first demonstration of crosstalk between these two family members. BTLA/HVEM interaction negatively modulates T cell activation. HVEM induces BTLA tyrosine phosphorylation and inhibits T-cell proliferation. There is accumulating evidence suggesting that BTLA/HVEM signaling also plays an important role in autoimmunity and infection at mucosal surfaces. The BTLA/HVEM interaction does not prevent the simultaneous binding of other HVEM ligands such as LIGHT or Lymphotoxin-alpha. BTLA is expressed on T cells, B cells, macrophages, dendritic cells, and natural killer cells. Constitutive expression level of BTLA on resting T cells are very low, but increase after the activation of T cells. BTLA is highly expressed on resting B cells.

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.
