Nemvaleukin alfa

• CAT Number: I041568
• CAS Number: 2315268-27-8
• Purity: ≥95%

Nemvaleukin alfa (ALKS 4230) is a IL-2 fusion protein that selectively binds to intermediate-affinity IL-2R. Nemvaleukin alfa is an activator of NK and effector T cells. Nemvaleukin alfa can be used for research of cancer[1][2][3].
Nemvaleukin alfa activates lymphocyte subsets from cynomolgus monkey and human samples, with EC50s of 0.45-2.2 nM[2].
Nemvaleukin alfa (0-100 nM, 30 min) induces the activation of intermediate-affinity IL-2R on human cells (HH cells)[3].
Nemvaleukin alfa (0-100 nM, 30 min) induces pSTAT5 in NK cells with an EC50 of 0.45 nM[3].
Nemvaleukin alfa (0.5 nM, 5 days) induces the activation of effector lymphocytes isolated from human peripheral blood[3].
Nemvaleukin alfa (6 mg/kg, s.c., every 4 days) inhibits SCLC tumor growth in mice[1].
