Alexa Fluor® 647 Mouse Anti-Rat IFN-γ
Alexa Fluor® 647 Mouse Anti-Rat IFN-γ
Flow cytometric analysis of IFN-γ expression by stimulated CD4+ rat splenocytes. Purified splenic CD4+ cells from Lewis rats were stimulated with plate-bound Purified NA/LE Mouse Anti-Rat CD3 (10 μg/ml; Cat. No. 554829) and soluble Purified NA/LE Mouse Anti-Rat CD28 (2 μg/ml; Cat. No. 554993) for 2 days in complete medium with Recombinant Rat IL-2 (10 ng/ml; Cat. No. 555106) and Recombinant Rat IL-4 (40 ng/ml; Cat. No 555107). Cells were harvested and cultured for 3 days in the presence of IL-2 (10 ng/ml) and IL-4 (20 ng/ml). This was followed by a 6 hour stimulation with Phorbol 12-Myristate 13-Acetate (PMA; 5 ng/ml; Sigma, Cat. #P-8139) and Ionomycin (500 ng/ml; Sigma, Cat. #I-0634) in the presence of GolgiPlug™ Protein Transport Inhibitor (Containing Brefeldin A) (2 μM; Cat. No. 555029). The cells were then fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655), and permeabilized with BD Perm/Wash™ Buffer (Cat. No. 554723), and subsequently stained with either Alexa Fluor® 647 IgG1, κ Isotype Control (Cat. No. 557732, Left Panel) or Alexa Fluor® 647 Mouse Anti-Rat IFN-γ antibody (Middle and Right Panel, Cat. No. 562213) by using BD Biosciences Intracellular Cytokine Staining Protocol. To demonstrate the specificity of staining, the binding of the Alexa Fluor® 647 Mouse Anti-Rat IFN-γ antibody was blocked by preincubation of cells with the Purified Mouse Anti-Rat IFN-γ antibody (Clone DB-1; Right Panel) prior to staining. Flow cytometric fluorescence dot blots showing the expression of IFN-γ (or Ig Isotype background staining) versus cellular autofluorescence (measured in the FL2 channel) were derived from gated events with the forward and side light-scatter characteristics of intact splenocytes. Flow cytometry was performed using a BD™ LSR II Flow Cytometer System.

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.

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.
