DR3, also known as TNFRSF25, lymphocyte-associated receptor of death (LARD), WSL-1, TRAMP, TR3 and APO3, is a 55 kD glycoprotein belonging to the TNF receptor superfamily (TNFRSF). TNFSF25 is expressed at low level on CD4-positive, CD8-positive T cells and NKT cells. It has been shown to stimulate NF-κB activity and regulate cell apoptosis. The signal transduction of this receptor is mediated by various death domains containing adaptor proteins. Recently, it has been shown that TNFRSF25 is also expressed on Treg cells and regulates Treg proliferation.Product Details
- Antibody Type
- Host Species
- Armenian Hamster
- Mtnfr25-Ig fusion protein
- 0.2 µm filtered in phosphate-buffered solution, pH 7.2, containing no preservative. Endotoxin level is <0.01 EU/µg of the protein (<0.001 ng/µg of the protein) as determined by the LAL test.
- The Ultra-LEAF™ (Low Endotoxin, Azide-Free) antibody was purified by affinity chromatography.
- The antibody is bottled at the concentration indicated on the vial, typically between 2 mg/mL and 3 mg/mL. Older lots may have also been bottled at 1 mg/mL. Please contact technical support for concentration and total µg amount, or use our Lookup tool if you have a lot number.
- Storage & Handling
- The antibody solution should be stored undiluted between 2°C and 8°C. This Ultra-LEAF™ solution contains no preservative; handle under aseptic conditions.
FC - Quality tested
Agonist - Verified
- Recommended Usage
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
4C12 is an agonistic antibody. It leads to rapid and selective proliferation of pre-existing Tregs in vivo through TCR engagement with MHC class II (MHC-II) and IL-2 signaling. We recommend our Ultra-LEAF™ purified 4C12 antibody (Cat. No. 144411 and 144412) for agonist or in vivo studies.

- 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.
- 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 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.
