A15105B_ULEAF_S100A8slashA9_Heterodimer_Antibody_052517
Recombinant human S100A8/A9 heterodimer stimulates proliferation of astrocytes in a dose-dependent manner (black circles). Proliferation induced by human S100A8/A9 heterodimer is neutralized (purple circles) by increasing concentrations of anti-human S100A8/A9 monoclonal antibody (Clone A15015B). The ND50 is typically 2 - 8 µg/mL.

Description

S100A8/A9, also known as Calprotectin, is a heterodimeric protein that belongs to the family of low molecular weight, calcium binding S100 proteins with two EF-hand calcium binding domains. Calcium and zinc binding influences the S100A8/A9 conformation and oligomerization state, which includes the self-assembly into homo- and heterodimers and larger oligomers. S100A8/A9 is elevated in blood and other body fluids in many pathological conditions including rheumatoid arthritis, inflammatory bowel diseases, viral or microbial infections, and tumors. S100A8/A9 is identified as an endogenous activator of TLR4 and is involved in promoting the inflammatory response in infections. Neutrophil-derived S100A8/A9 inhibits growth of Staphylococcus aureus through the chelation of manganese and zinc. S100A8/A9 is also identified as a potent amplifier of inflammation in autoimmunity as well as in cancer development and tumor spread. Injury induced by S100A8/A9 stimulates IP-10 production in monocytes and macrophages. In addition, the S100A8/A9 heterodimer also promotes astrocyte proliferation.

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.
