    Recombinant mouse BAFFR (Black Circles, Cat. No. 756506) binds to immobilized recombinant mouse BAFF (Cat. No. 591202). Anti-mouse BAFFR antibody (Purple Squares, Clone 7H22-E16) inhibits the binding in a dose-dependent manner. This antibody blocks the binding of 0.2 µg/mL recombinant mouse BAFF protein to 1 µg/mL of immobilized recombinant mouse BAFFR with an ND50 = 0.15-1.5 µg/mL.

BAFF (B cell-activating factor belonging to the TNF family) receptor (BAFF-R) is one of the three receptors that bind to BAFF. It is a type III transmembrane TNF receptor family member. BAFF-R is expressed at high levels in resting B cells and at lower levels in activated B cells, a small subset of activated/memory CD4+ T cells. It is a major mediator of BAFF dependent co-stimulatory response in peripheral B and T cells. It was reported that the mice expressing defective BAFF-R have disrupted B cell maturation. BAFF receptor appears to be particularly important for the regulation of normal B cell survival and maturation, as well as in the pathophysiology of aggressive B-cell malignancies and autoimmune diseases.

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 ≤ 0.25 µg per million cells in 100 µl volume. The antibody blocks the binding between recombinant mouse BAFF (Cat. No. 591202) and recombinant mouse BAFFR (Cat. No. 756506). The ND50 range is 0.15 - 1.5 μg/mL. It is recommended that the reagent be titrated for optimal performance for each application.

Related FAQs

Does BioLegend test each LEAF™ antibody by functional assay?

No, BioLegend does not test 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 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 LEAF™/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.
