Alexa Fluor® 647 Rat Anti-Mouse IFN-γ
Alexa Fluor® 647 Rat Anti-Mouse IFN-γ

Analysis for IFN-γ in stimulated CD4+ and CD4 BALB/c spleen cells. Splenocytes from BALB/C mice were stimulated for 4 hrs with PMA (5 ng/ml, Sigma Cat. No. P-8139) and Ionomycin (500 ng, Sigma Cat. No. I-0634) in the presence of Brefeldin A (GolgiPlug, Cat. No. 555029). Cells were harvested, fixed, permeabilized and stained with PE Rat Anti-Mouse CD4 (Cat. No. 553048) and either the Alexa Fluor® 647 Rat Anti-Mouse IFN-γ antibody (left panel) or with a Alexa Fluor® 647 Rat IgG1 isotype control (Cat. No. 557731), (right panel). To demonstrate specificity of the staining, the binding of the Alexa Fluor® 647 Rat Anti-Mouse IFN-γ antibody (XMG1.2) was blocked by preincubation of the fixed/permeabilized cells with an excess of unlabelled XMG1.2 antibody (5 µg, Cat. No. 554409, data not shown) prior to stainining. The quadarant markers for the bivariate dot plots were set based on the autofluorescence and isotype controls.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.

XMG1.2

The XMG1.2 monoclonal antibody specifically binds to mouse interferon-γ (IFN-γ) protein. IFN-γ is a pleiotropic cytokine, of approximately 15-17 kDa, involved in the regulation of inflammatory and immune responses. It plays an important role in activation, growth, and differentiation of T and B lymphocytes, macrophages, NK cells and other non-hematopoietic cell types. IFN-γ production is associated with the Th1 cell differentiation. The purified form of this antibody has been reported to be a neutralizing antibody.

Alexa Fluor™ 647
Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 520-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.
