The ED50 was determined by the ability to inhibit the IL-1alpha mediated cell proliferation in a murine helper T cell line,for this effect, in the presence of 50 pg/mL of IL-1alpha, is typically 20 - 60 ng/mL.
Lyophilized from PBS, pH 7.4

The protein encoded by this gene is a member of the interleukin 1 cytokine family. This protein inhibits the activities of interleukin 1, alpha (IL1A) and interleukin 1, beta (IL1B), and modulates a variety of interleukin 1 related immune and inflammatory responses. This gene and five other closely related cytokine genes form a gene cluster spanning approximately 400 kb on chromosome 2. A polymorphism of this gene is reported to be associated with increased risk of osteoporotic fractures and gastric cancer. Four alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq
