Clone Host Grade Applications
Polyclonal Rabbit Highly Purified E B IH FC N
IL-1alpha is a non-secreted proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells
This antibody is primarily directed against the 17kD human IL-1a. In general,this antibody also detects primate IL-1a in the same formats using similar dilutions. The antiserum does not recognize human IL-1b or Mouse or Rabbit IL-1a. In ELISA formats and other immunoreactive assays, this antibody will recognize both the mature 17kD IL-1a as well as the 31kD IL-1a precursor in either non-denatured (native) or denatured samples.
Unlike the IL-1b precursor, the native precursor of IL-1a is recognized by the antibody produced to the 17kD form. The
31kD precursor of IL-1a is biologically active and is found primarily intracellularly. The precursor of IL-1a, unlike that of IL-
1b, is biologically active when applied to cells and is thought to have a role as a functional molecule intracellularly and can be
found constitutively expressed in various cell. This antibody is also useful for neutralization of human and primate IL-1a
activity in bioassays. It does not neutralize the biological activity IL-1b. It does not neutralize the biological activity of mouse,
rat or rabbit IL-1a. It will neutralize primate IL-a.
