Mouse IFN-gamma Antibody

Detection of IFN‑ gamma in Mouse Splenoctyes by Flow Cytometry. Mouse splenocytes either (A) stimulated to induce Th1 cells or (B) unstimulated were stained with Rat Anti-Mouse IFN-gamma Monoclonal Antibody (Catalog # MAB485) followed by Phycoerythrin-conjugated Anti-Rat IgG Secondary Antibody (F0105B) and Rat Anti-Mouse CD4 APC-conjugated Monoclonal Antibody (FAB554A). Quadrant markers were set based on control antibody staining (MAB006). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (FC005).

Quadrant markers were set based on control antibody staining (MAB006). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (FC005). Staining was performed using our Staining Intracellular Molecules protocol.

IFN‑ gamma Inhibition of EMCV-induced Cytopathy and Neutralization by Mouse IFN‑ gamma Antibody. Recombinant Mouse IFN-gamma 485-MI) reduces the Encephalomyocarditis Virus (EMCV)-induced cytopathy in the L-929 mouse fibroblast cell line in a dose-dependent manner (orange line), as measured by crystal violet staining. Inhibition of EMCV activity elicited by Recombinant Mouse IFN-gamma (2.5 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse IFN-gamma Monoclonal Antibody (Catalog # MAB485). The ND₅₀ is typically 0.075-0.3 µg/mL.

Detection of IFN‑ gamma in Mouse Spleen. IFN‑ gamma was detected in immersion fixed paraffin-embedded sections of Mouse Spleen using Rat Anti-Mouse IFN‑ gamma Monoclonal Antibody (Catalog # MAB485) at 10 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Rat IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC005). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in lymphocytes.

Mouse numbers (n) and P values (paired two-tailed Student's t-test) are indicated. (e,f) Cytokine-producing cells among CD4 cells from draining LN (e) and CNS (f) on days 13–18 after MOG immunization. Left panels: representative dot plots; right panel: bar graphs (means±s.e.m.) summarizing all the results, with mouse numbers and P values (two-tailed Student's t-test) indicated. (g) HE (left column) or Luxol Fast Blue (right column) staining of spinal cords 30 days after MOG immunization. Asterisks indicate cell infiltration. Arrows point to demyelination. (h) Means±s.e.m. of mononuclear cell infiltration scores, demyelination scores and total pathological scores, which is the sum of the first two scores. Mouse numbers (n) and P values (two-tailed Student's t-test) are indicated. (i) Treg cells in naive KO mice on day 17 during EAE induction. Left panel: representative dot plots; right panel: means±s.e.m. of data from three experiments. NS: not significant (two-tailed Student's t-test).
