IL‑2 was detected in immersion fixed rat splenocytes stimulated with calcium ionomycin and PMA using Goat Anti-Rat IL‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-502-NA) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

IL‑2 was detected in immersion fixed frozen sections of rat spleen using Goat Anti-Rat IL‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-502-NA) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in lymphocytes. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Recombinant Rat IL‑2 (Catalog # 502-RL) stimulates proliferation in the CTLL‑2 mouse cytotoxic T cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Rat IL‑2 (2 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Rat IL‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-502-NA). The ND50 is typically 0.15-0.75 µg/mL.
