Flow cytometric analysis of intracellular IL-6 expression by activated mouse macrophages. Thioglycollate-elicited mouse peritoneal macrophages were primed with recombinant mouse IFN-γ (10 ng/ml, Cat. No. 554587) for 2 hr and stimulated overnight with lipopolysaccharide (LPS, Sigma, Cat. No. L-8272; 1 μg/ml) and BD GolgiPlug™ Protein Transport Inhibitor (Containing Brefeldin A) (Cat. No. 555029). The adherent cells were washed with 1× phosphate buffered saline (PBS) and incubated with 1× trypsin-EDTA solution (37°C, 15 min). The cells were harvested, washed, incubated with Fc Block™ (Rat IgG2b,κ Anti-Mouse CD16/CD32) antibody (Cat. No. 553142), fixed and permeabilized using BD Cytofix™ Fixation Buffer (Cat. No. 554655) and BD Perm/Wash™ Buffer (Cat. No. 554723). The cells were then stained either with an Alexa Fluor® 488 Rat IgG1, κ Isotype Control (Cat No. 557720, Left Panel) or with the Alexa Fluor® 488 Rat Anti-Mouse IL-6 antibody (Cat No. 561363, Right Panel). MiCK-3 Mouse Cytokine Positive Control Cells (Cat No. 554654) are prepared in a similar manner. These cells can be used as a positive control for cytokine flow cytometry experiments designed to characterize the nature of mouse IL-6-producing cells. Two-color flow cytometric dot plots showing the correlated expression of IL-6 (or Ig Isotype control staining) versus cellular autofluorescence measured in the phycoerythrin channel (autofluorescence) were derived from events with the forward and side light-scatter characteristics of intact macrophages. 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® 488 under optimum conditions, and unreacted Alexa Fluor® 488 was removed.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
- Alexa Fluor® is a registered trademark of Molecular Probes, Inc., Eugene, OR.
- The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Format Details
Alexa Fluor™ 488
Alexa Fluor™ 488 Dye is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 517-nm. Alexa Fluor™ 488 is designed to be excited by the Blue laser (488 nm) and detected using an optical filter centered near 520-nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
