Recombinant Mouse IL‑2 (Catalog # 402-ML) stimulates proliferation in the CTLL‑2 mouse cytotoxic T cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse IL‑2 (2 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse CD25/IL‑2 R alpha Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2438). The ND50 is typically 5-20 µg/mL.
CD25/IL‑2 R alpha was detected in immersion fixed frozen sections of mouse spleen using 5 µg/mL Goat Anti-Mouse CD25/IL‑2 R alpha Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2438) overnight at 4 °C. Tissue was stained with the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained (green).
