Poly5160_LEAF_TNF-a_Antibody_1_020821
Recombinant mouse TNF-α (Cat. No. 575206) (black circles) cytotoxicity on 929L mouse musculus cells. LEAF™ purified anti-mouse/rat TNF-α antibody (Poly5160) (purple squares) neutralizes the cytotoxicity function of recombinant mouse TNF-α (Cat. No. 575206) at 0.04 ng/mL on 929L cells in a dose-dependent manner whereas the GoInVivo™ purified goat IgG isotype ctrl antibody (gray triangles) does not have the effect. ND50 range: 0.05 - 0.25 µg/mL.

    Whole cell extracts (15 µg protein) from RAW264.7 cells that were pre-treated with 300 ng/mL brefeldin A solution (Cat. No. 420601) for 3 hours and unstimulated (-) or stimulated (+) with 100 ng/mL LPS for 6 hours were resolved on a 4-12% Bis-Tris gel, transferred to a PVDF membrane, and probed with a 1:5000 dilution of LEAF™ purified anti-mouse/rat TNF-α antibody (Poly5160) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP donkey anti-goat IgG antibody at a 1:10000 dilution. Equal protein loading was confirmed using HRP anti-β-actin antibody.

Description

TNF-α is secreted by macrophages, monocytes, neutrophils, T-cells (principally CD4+), and NK-cells. Many transformed cell lines also secrete TNF-α. Monomeric mouse TNF-α is 156 amino acid protein (N-glycosylated) with a reported molecular weight of 17.5 kD protein. TNF-α forms multimeric complexes; stable trimers are most common in solution. A 26 kD membrane form of TNF-α has also been described. TNF-α binding to surface receptors elicits a wide array of biologic activities including: cytolysis and cytostasis of many tumor cell lines in vitro, hemorraghic necrosis of tumors in vivo, increased fibroblast proliferation, and enhanced chemotaxis and phagocytosis in neutrophils.

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.
