Human IFN-γ Recombinant Protein
简单描述
The B27 monoclonal antibody specifically binds to human interferon-γ (IFN-γ), a 14-18 kDa glycoprotein containing 143 amino acid residues. IFN-γ is a potent multifunctional cytokine produced by several activated cell types including NK, NKT, CD4+TCRαβ+, CD8+TCRαβ+, and TCRγδ+ T cells. IFN-γ exerts its biological effects through specific binding to the high-affinity IFN-γ receptor complex comprised of IFN-γRα (CD119) and IFN-γRβ subunits. In addition to its antiviral effects, IFN-γ upregulates a number of lymphoid cell functions including the antimicrobial and anti-tumor responses of macrophages, NK cells, and neutrophils. In addition, IFN-γ influences the regulation of proliferation, differentiation, and effector responses of B cell and T cell subsets. These influences can involve IFN-γ's capacity to boost MHC class I and II expression by antigen-presenting cells as well as direct effects on B cells and T cells themselves. B27 is a neutralizing antibody. The use of B27 antibody for epitope mapping of human IFN-γ has been described. The B27 antibody has been reported not to bind to denatured IFN-γ.

APC
Allophycocyanin (APC), is part of the BD family of phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 651 nm and an emission maximum (Em Max) at 660 nm. APC is designed to be excited by the Red (627-640 nm) laser and detected using an optical filter centered near 660 nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Expression of IFN-γ by stimulated human peripheral blood mononuclear cells (PBMC). Human PBMC were stimulated for 6 hours with PMA (50 ng/ml final concentration; Sigma, Cat. No. P-8139) and calcium ionophore A23187 (250 ng/ml final concentration; Sigma, Cat. No. C-9275) in the presence of GolgiStop™ (Cat. No. 554724). The PBMC were stained with PE-Cy5 anti-CD3 (Cat. No. 555334/561007), fixed and permeabilized with BD Cytofix/Cytoperm Plus Kit (with BD GolgiStop) (Cat. No. 554715), then subsequently stained with 0.25 μg of APC Mouse Anti-Human IFN-γ antibody (Cat. No. 562017/554702). To demonstrate specificity of staining, binding by the APC Mouse Anti-Human IFN-γ antibody was blocked by preincubation of fixed/permeabilized cells with excess Purified Mouse Anti-Human IFN-γ antibody (5 ug; Cat. No. 554699/550011; right panel). The quadrant markers for the bivariate dot plot were set based on autofluorescence controls, and verified using the unlabeled B27 antibody blocking control.
