A18209D_ULEAF_CD27_Antibody_031621
Recombinant mouse CD27L (Cat. No. 550406) (black circles) binds to immobilized recombinant mouse CD27 (TNFRSF7)-Fc chimera (Cat. No. 765604). Ultra-LEAF™ purified anti-mouse CD27 antibody (clone A18209D) (purple squares) inhibits the binding in a dose-dependent manner whereas the GoInVivo™ purified rat IgG2a, κ isotype ctrl antibody (Cat. No. 400562) (gray triangles) does not have the effect. This antibody blocks the binding of 0.08 µg/mL recombinant mouse CD27L to 2 µg/mL immobilized recombinant mouse CD27 (TNFRSF7)-Fc chimera. ND50 = 0.3 - 1.5 µg/mL.

Description

CD27 (TNFRSF7) is a member of the TNFR family. It is a type I membrane glycoprotein with a MW of 55 kD that forms a disulfide‑linked homodimer. The receptor possesses three cysteine rich repeats in the extracellular domain, the transmembrane region, and the intracellular domain. CD27 binds CD27L (CD70), another member of the TNF ligand family that forms a trimer; thus, it has been speculated that the CD27L binds to a trimeric structure composed by three dimeric CD27 molecules. The interaction between CD27 and its ligand, CD70, plays a role in providing co-stimulation for prolonged lymphocyte survival, enhanced T-cell proliferation, and memory-cell formation. T cells expressing CD27 and CD70 play a key role in regulating B-cell activation and immunoglobulin synthesis. Soluble CD27 (sCD27), the extracellular domain of membrane-bound CD27, can be released after lymphocyte activation by differential splicing of the receptor protein or shedding from the cell surface by metalloproteinases (MMPs). Soluble CD27 has been detected in serum, plasma, and urine samples from healthy individuals, and it has been described elevated sCD27 levels in serum of patients with systemic lupus erythematosus, viral infections, and lymphoid malignancies. The sCD27-pool in cancer patients can be significantly enlarged by immunotherapy. CD27 is recognized as a marker for memory B cells and is considered of diagnostic value in patients who have decreased numbers of switched memory 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.
