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 also exerts anti-proliferative, immunoregulatory, and proinflammatory activities. IFN-γ can upregulate MHC class I and II antigen expression by antigen-presenting cells. The 4S.B3 antibody reacts with the human IFN-γ. The NIB42 antibody can neutralize the bioactivity of natural or recombinant IFN-γ.

- Application
-
ELISA Capture - Quality tested
ELISPOT Capture, Neut - Reported in the literature, not verified in house - Recommended Usage
-
Each lot of this antibody is quality control tested by ELISA assay. For ELISA capture applications, a concentration range of 1.0 - 4.0 µg/ml is recommended. To obtain a linear standard curve, serial dilutions of IFN-γ recombinant protein ranging from 1000 to 8 pg/ml are recommended for each ELISA plate. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
-
ELISA or ELISPOT Capture2: The purified NIB42 antibody is useful as the capture antibody in a sandwich ELISA, when used in conjunction with the biotinylated 4S.B3 antibody (Cat. No. 502504/502514) as the detecting antibody. The Ultra-LEAF™ purified antibody is suggested for ELISPOT capture. For ELISPOT capture applications, a concentration range of 0.5 - 2.0 µg/ml is recommended.
Neutralization1: The Ultra-LEAF™ purified antibody (Endotoxin <0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for neutralization of human IFN-? bioactivity (Cat. No. 502405 & 502406).
Note: For testing human IFN-? in serum or plasma, BioLegend's ELISA Max™ Sets (Cat. No. 430101 to 430106) are specially developed and recommended. -
