There is great interest in identifying downstream T cell responses following immune checkpoint blockade to direct more effective treatments and better-informed therapeutic decisions. R&D Systems and Tocris offer a wide selection of reagents, kits, and assays that will allow you to explore, modulate, and validate T cell responses downstream of immune checkpoint blockade.
Analyze the expression levels or phosphorylation status of up to 111 proteins simultaneously. Imagine the time you’ll save investigating how your checkpoint blockade affects downstream responses!
|Cytokine Profile of TNF-alpha-treated Balb/3T3 Cells. Balb/3T3 mouse embryonic fibroblast cells were untreated or treated with 100 ng/mL of Recombinant Mouse TNF-alpha (Catalog # 410-MT) for 24 hours. Cell supernates were analyzed using the Mouse XL Cytokine Array Kit (Catalog # ARY028).

|Detection of IFN-gamma in Human PBMCs. Human PBMCs were stimulated with PMA (Catalog # 1201) and ionomycin. IFN-gamma was detected using Human IFN-gamma Monoclonal Antibody (Catalog # MAB285). Cells were stained with the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue).||Detection of TNF-alpha in Mouse T Cells. TNF-alpha was detected in immersion fixed activated mouse T cells using Mouse TNF-alpha Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-410-NA). Cells were stained (red) and counterstained (green).||Detection of Phospho-p38 by Western blot. Lysates of HepG2 human hepatocellular carcinoma cells were untreated (-) or treated (+) with 20 ng/mL Recombinant Human IL-1 beta (Catalog # 201-LB) for the indicated times. The PVDF membrane was probed with Rabbit Anti-Human/Mouse/Rat Phospho-p38 MAP Kinase (T180/Y182) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF869), followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008).|
Identify and measure the frequency of cytokine secreting cells with the most accurate and sensitive ELISpot kits available. Our single and dual-color complete ELISpot kits are ready-to-run out of the box and require no assay development. Alternatively, we offer ELISpot Development Modules that contain the basic components required to develop your own ELISpot assay.
|Identification of IFN-gamma- and IL-17-Secreting Cells. IFN-gamma (blue spots) and IL-17 (red spots) were secreted from mouse splenocytes stimulated with PMA/Ca2+ ionomycin. Spots of cytokine secretion were visualized using the Mouse IFN-gamma/IL-17 Dual-Color ELISpot Kit (Catalog # ELD5007).
