  • Patent number: 6232087
    Abstract: The subject invention concerns a novel selective, sensitive, and highly reliable immunoassay for detecting human IL-1&bgr; in cultured mononuclear cells or human body fluids. It is a competitive immunoassay which is useful in diagnostic work to detect IL-1&bgr; selectively, for the first time, from among similar lymphokines and other substances known to interfere with bioassays for IL-1.
    Type: Grant

  • Patent number: 5908754
    Abstract: The present invention is directed to an in vitro method of determining the in vivo EPO activity of a sample containing EPO. More particularly, the present method comprises treating a sample containing EPO under conditions which remove desialylated EPO, and measuring the in vitro EPO activity of the resulting treated sample. In a preferred embodiment, desialylated EPO is removed from the sample by incubating the sample with cells of the human hepatoma cell line HepG2, and in vitro EPO activity is determined by incubating the treated sample with cells of an EPO-responsive cell line and measuring the proliferation or viability of the EPO-responsive cells. The present invention is useful, for example, in quantitating the biologically active EPO in a variety of sample types.
