Regulatory Status Legend
The JES3-9D7 monoclonal antibody specifically reacts with human IL-10 (Interleukin-10) and viral IL-10. The immunogen used to generate the JES3-9D7 hybridoma was recombinant human IL-10 expressed by COS cells. IL-10 is also known as CSIF (Cytokine synthesis inhibitory factor) and (TGIF) T-cell growth inhibitory factor. IL-10 is expressed by various cell types including activated monocytes, macrophages, dendritic cells, mast cells, granulocytes, and lymphocytes. IL-10 is a pleiotropic cytokine that can downregulate proinflammatory immune responses, such as Th1-like responses, while promoting other responses including B cell proliferation and antibody production.

R-phycoerythrin (PE) is an accessory photosynthetic pigment found in red algae. It exists in vitro as a 240-kDa protein with 23 phycoerythrobilin chromophores per molecule. This makes PE one of the brightest fluorochromes for flow cytometry applications, but its photobleaching properties make it unsuitable for fluorescence microscopy.

Preparation and Storage
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- 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.
Immunofluorescent Staining and Flow Cytometric Analysis: The PE-conjugated JES3-9D7 antibody can be used for multicolor immunofluorescent staining and flow cytometric analysis to identify and enumerate IL-10-producing cells within mixed cell populations (see image). This 100 Test Size formulation of the PE-conjugated JES3-9D7 antibody has been pre-titrated to assure effective intracellular detection of human and viral IL-10 using 20 µl/1 x 10^6 cells. A useful control for demonstrating specificity of staining is either of the following: 1) pre-block the conjugated JES3-9D7 antibody with ligand (recombinant human IL-10; Cat. No. 554611) prior to staining, or 2) pre-block the fixed/permeabilized cells with unlabeled JES3-9D7 antibody (Cat. No. 554496) prior to staining. The staining technique and use of blocking controls are described in detail by C. Prussin and D. Metcalfe. A suitable rat IgG1 isotype control for assessing the level of background staining on paraformaldehyde-fixed/saponin-permeabilized human cells is also available in a 100 Test Size formulation PE-R3-34 (Cat. No. 559318). For specific methodology, please visit the protocols section or chapter on intracellular staining in the Immune Function Handbook, both of which are posted on our web site, www.bdbiosciences.com.
Important Note: This pretitered antibody solution does not contain a cell permeabilization agent. It is necessary to include a cell permeabilization agent when using the pre-titered antibody solution to stain fixed and permeabilized cells. Perm/Wash™ Buffer (Cat. No.554723) contains the permeabilization agent saponin and is useful for this purpose as described in the USAGE section below.
1. Resuspend 1 x 10^6 fixed and permeabilized cells in 20 µl of the pre-titered antibody solution and 30 µl of 1X Perm/Wash™ Buffer (Cat. No. 554723).
2. Incubate the cell suspension for 15 minutes (at RT or 4°C).
3. Wash twice in 100 µl of 1X Perm/Wash™ Buffer (Cat. No. 554723).
