    摘要: A recombinant human IL-12 receptor complex produced on the surface of a non-human mammalian cell and free from other human proteins, the complex comprising the beta1 receptor protein complexed with a beta2 receptor protein, which complex is capable of binding to human IL-12 with high affinity. A recombinant human IL-12 beta2 receptor protein produced on the surface of a non-human mammalian cell, free from other human proteins, in its active form. In addition, a non-human mammalian cell having expressed on its surface the recombinant human IL-12 beta2 receptor protein or the recombinant human IL-12 receptor complex, which cell proliferates in the presence of human IL-12. A non-human mammalian cell having the human IL-12 beta2 receptor protein or the complex expressed on its surface and which proliferates in response to human IL-12 is useful for determining whether a given compound inhibits biological activity of human IL-12 or is an IL-12 agonist.
