Purified Rat Anti-Mouse IL-10
Purified Rat Anti-Mouse IL-10

Immunocytochemistry on stimulated cells. RBC-lysed BALB/c splenocytes were enriched in CD4+ cells by panning and were cultured for 2 days with plate bound anti-mouse CD3 and soluble anti-mouse anti-CD28 in the presence of recombinant mouse IL-2 and recombinant mouse IL-4. The cells were subsequently harvested, washed and recultured with recombinant  mouse IL-2 and recombinant mouse IL-4 for an additional 3 days. Finally, the cells were harvested, washed and cultured with PMA (Sigma, 5 ng/ml) and ionomycin (Sigma, 500 ng/ml) in the presence of GolgiPlug™ (Cat. No. 555029) for 4 hr at 37°C. The activated cells were harvested and the presence of IL-10 producing cells was detected by immunocytochemistry using a three-step staining procedure that employs a Biotin Goat anti-Rat IgG secondary antibody (Cat. No. 559286) and a horseradish peroxidase-based detection system (Cat. No. 550946) (Nomarski optics, original magnification 400 X). To demonstrate specificity of staining the binding of the Purified Rat Anti-Mouse IL-10 (Cat. No. 559063) antibody was blocked by the preincubation of the purified antibody with excess recombinant mouse IL-10 protein (Cat. No. 550070; data not shown).

Recommended Assay Procedures

Immunocytochemistry: The ICC format of the purified JES5-16E3 (Cat. No. 559063) antibody can be used to identify and enumerate IL-10 producing cells by immunocytochemistry. For optimal indirect immunocytochemical staining, the JES5-16E3 antibody should be titrated (≤ 1 µg) and visualized via a three-step staining procedure utilizing biotin goat anti-rat IgG and an avidin/streptavidin- horseradish peroxidase conjugate. A detailed protocol for the cytokine immunocytochemical procedure is included below.

PROCEDURE FOR IMMUNOCYTOCHEMICAL STAINING OF SINGLE-CELL PREPARATIONS

This procedure describes the immunoenzymatic technique of staining cytokines within individual cells that are immobilized on microscopic slides via adherence (adherent slides) or centrifugation (cytospins).  

ADHESION SLIDES

1. Harvest cells and wash them twice in PBS using centrifugation (400 x g for 5 min) to remove residual protein.

2. Adjust the cell concentration at 4-5 x 10e6 cells/ml in PBS.

3. Place 20 µl of the cell suspension in each well of the adhesion slides and let them adhere at room temperature (RT) for 20 min. Please note that the slides should be washed in PBS at RT for 5 min before transferring the cells.

4. Fix cells on slides using fixation buffer for 15 min at RT.

5. Wash slides 2X in PBS with 5 min incubations.

6. Block slides with PBS supplemented with 1% (w/v) BSA (Sigma, Cat. No. A43-78) for 30 min at RT or 10 min at 37°C.

7. Wash slides 2X in PBS and proceed with staining or air dry them and store them at -80°C for future use.

8. Incubate slides with 20 µl of 1% goat serum and PBS with 0.1% (w/v) saponin for 30 min at RT.

9. Wash slides 2X with PBS with 5 min incubations.

10. Block endogenous peroxidase activity with Endogenous Peroxidase Blocking Buffer (20 µl/well) for 10 min at RT.

11. Wash 2X in PBS with 5 min incubations.

12. Incubate each well with Avidin (20 µl/well) for 15 min.

13. Wash 2X in PBS with 5 min incubations.

14. Incubate each well with Biotin (20 µl/well) for 15 min.

15. Wash 2X in PBS with 5 min incubations.

16. Incubate each well for 1 hr at RT with 20 µl of purified cytokine-specific antibody or appropriate immunoglobulin isotype control diluted in BD Pharmingen IHC Diluent Buffer (Cat. No. 559148), supplemented with saponin.

17. Wash slides 2X in PBS with 5 min incubations.

18. Incubate each well with 20 µl of a biotinylated secondary antibody diluted in IHC Diluent Buffer with saponin for 30 min at RT.

19. Wash 2X in PBS with 5 min incubations.

20. Apply 20 µl of Streptavidin-HRP (BD Cat. No. 550946)  to each well on slides and incubate for 30 min at RT.

21. Wash slides 2X with PBS with 5 minutes incubations.

22. Incubate with DAB Substrate as directed, (BD Cat. No. 550880) for less than 5 min at RT.

23. Stop the development of the color reaction by washing with PBS.

24. The slides are subsequently mounted in short-term storage mounting medium.

CYTOSPINS

1. Assemble the Cytospin's sample chamber (e.g. Cytospin 3, Shandon, UK or comparable centrifuge), filter card, slide and cytospin racks according to manufacturer's specifications.

2. Load 40 µl of approximately 1 x 10e6 cells to each sample chamber.

3. Spin slides at 600 rpm for 2 min.

4. Take slides out of the cytospin rack and place them on a staining rack.

5. For fixation and staining please follow the steps 4 through 24 specified above for staining cells on adhesion slides.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
  3. 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.

JES5-16E3

The JES5-16E3 monoclonal antibody specifically binds to the mouse cytokine, Interleukin-10 (IL-10). IL-10 is also known as Cytokine Synthesis Inhibitory Factor (CSIF). It is produced by various activated cell types including CD4+ T cells, CD8+ T cells, T regulatory cells, NK T cells, B1 B cells, NK cells, macrophages, dendritic cells, mast cells, granulocytes and keratinocytes. IL-10 plays a pivotal role in regulating immune responses and protecting the host from damage caused by inflammatory and autoimmune responses. IL-10 has numerous biological activities including the inhibition of cytokine synthesis by activated T cells, NK cells, monocytes, and macrophages. In the presence of accessory cells, IL-10 inhibits mitogen- or anti-CD3 induced proliferation of T lymphocytes.  IL-10 has also been shown to costimulate the development of thymocytes, B cell differentiation and the generation of cytotoxic T cells. The immunogen used to generate the JES5-16E3 hybridoma was recombinant mouse IL-10. JES5-16E3 is a neutralizing antibody.
