Biolegend, 358408, Ultra-LEAF™ Purified anti-human CD120b Antibody, 500μg

CD120b, also known as TNFRII or TNFRSF1B, belongs to the TNF receptor superfamily and can interact with ligands TNF-α and TNF-β (also known as LT-α). It is a 75 kD type I transmembrane protein expressed on lymphocytes, monocytes, and granulocytes. When present in a heterocomplex with CD120a, it induces the recruitment of anti-apoptotic molecules, c-IAP1 and c-IAP2 that possess E3 ubiquitin ligase activity. Mutations in CD120b are associated with TNF-associated periodic syndrome (TRAPS) or periodic fever syndrome.

Q: Do you guarantee that your antibodies are totally pathogen free?
A: 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.
Q: Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
A: 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.
Q: Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
A: 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.
Q: Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
A: 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.
