Expression of TNF by stimulated human peripheral blood lymphocytes. Human peripheral blood mononuclear cells were stimulated for 4 hours with PMA (5 ng/ml, Sigma, Cat. No. P-8139) and Ionomycin (500 ng, Sigma, P-8139) in the presence of Brefeldin A (GolgiPlug, Cat. No. 555029), Cells were harvested, fixed, permeabilized and stained with PE-conjugated mouse anti-human CD8 (PE-RPA-T8, Cat. No. 555367) and either mouse anti-human TNF antibody (Alexa Fluor® 488-MAb11, Cat. No. 557722), (left panel) or Alexa Fluor® 488-MOPC-21 immunoglobulin (Cat. No. 557721) (right panel) by using the staining protocol found in the protocols section at www.bdbioscience.com. To deomonstrate specificty of staining the binding of Alexa Fluor® 488-MAb11 was blocked by the preincubation of the conjugated antibody with molar excess of recombinant human TNF (Cat. No. 554618) and by preincubation of the fixed permeabilized cells with an excess of unlabelled MAb11 antibody (5 µg, Cat. No. 554510) prior to staining. Dot plots were derived from gated events with the forward and side light scatter characteristics of lymphocytes. The quadrant markers for the bivariate dot plots were set based on the autofluorescence and isotype controls.

Recommended Assay Procedure:
Immunofluorescent Staining and Flow Cytometric Analysis: The FITC-, PE-, APC-, PE-Cy7-, Alexa Fluor® 488-, and Alexa Fluor® 647-MOPC-21 immunoglobulins (Cat. No. 554679, 559320, 554681, 557646, 557721, and 557732) are suitable mouse IgG1κ isotype controls for assessing the level of background staining on paraformaldehyde fixed/saponin-permeabilized mouse or human cells for flow cytometric analysis.

The MOPC-21 immunoglobulin is a mouse myeloma protein. The MOPC-21 immunoglobulin was selected as an isotype control following screening for low background on a variety of mouse and human tissues.
Cat. no. 557721 has been optimized for assessing the level of background staining on paraformaldehyde fixed/saponin-permeabilized mouse or human cells for flow cytometric analysis. This antibody is routinely tested by flow cytometric analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.
