W19171A_ULEAF_IFN-Y_Neut_0421223
Recombinant human IFN-γ (Cat. No. 570206) (black circles) decreased the cell viability of HT-29 cells with recombinant human TNF-α (Cat. No. 570106) at 0.1 µg/mL. Ultra-LEAF™ purified anti-human IFN-γ (clone W19171A) (purple squares) reverses the effect of recombinant human IFN-γ at 0.08 µg/mL and recombinant human TNF-α at 0.1 µg/mL on HT-29 cells in a dose-dependent manner, whereas the Ultra-LEAF™ purified rat IgG2b, κ isotype control (Cat. No. 400644) (gray triangles) does not have the effect. ND50 range : 1 - 5 μg/mL

Description

Interferon-γ is a potent multifunctional cytokine which is secreted primarily by activated NK cells and T cells. Originally characterized based on anti-viral activities, IFN-γ demonstrates anti-proliferative, immunoregulatory, and proinflammatory activities. IFN-γ can upregulate MHC class I and II antigen expression by antigen-presenting 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.
